QA

Why might Increasing the concentration of a set of reactants increase the rate of reaction?

Increasing the concentration of the reactants will increase the frequency of collisions between the two reactants. When collisions occur, they do not always result in a reaction (atoms misaligned or insufficient energy, etc.). Higher concentrations mean more collisions and more opportunities for reaction.

What does increasing the concentration of the reactants speed up a chemical reaction?

The frequency of collisions between the two reactants will increase as their concentrations rise, though not always because of misaligned atoms or a lack of energy. Higher concentrations mean more collisions and more opportunities for reaction.

How does temperature increase the rate of a chemical reaction Quizizz?

The concentration of the reactants increases as the temperature rises, resulting in larger particle size of the reactants.
What factors increase the rate of reaction Quizizz?
A. Normally, lowering the temperature will slow down a reaction because the reactants have larger particle sizes, as increasing the temperature will increase the kinetic energy of particles and thereby increase the number of collisions between particles.

Because there are more collisions when the concentration is higher, reactions happen more quickly.
Why does a catalyst increase the rate of reaction Quizizz?
A. Adding a catalyst speeds up the rate of reaction for both the forward and reverse reactions. Increasing the concentration of a reactant may increase the rate of a reaction because it increases the number of collisions.
When the concentration of reactant molecules increases the rate of reaction increases what is the best explanation for this as the reactant concentration increases?
The best explanation for the relationship between reactant concentration and reaction rate is that (a) average kinetic energy of molecules increases as reactant concentration increases.
Which factors increase the rate of a reaction?
A reaction can be accelerated by adding a catalyst to the reaction mixture, increasing the temperature of the reaction system, increasing the surface area of a solid reactant, and increasing the concentration of a reactant in solution.
Which best defines reaction rate Quizizz?

  • Which definition best fits reaction rate?
  • A substance that speeds up chemical reactions without altering them is known as:
  • Chemical reactions need activation energy to begin.
  • One of the following things may happen if the reactants temperature rises.
  • Increasing a reacting vessels pressure only changes:

How does an increase in the temperature of a chemical reaction affect the reaction rate?
A decrease in temperature would have the opposite effect, resulting in fewer collisions. With an increase in temperature, there is an increase in energy that can be converted into activation energy in a collision, and that will increase the reaction rate.

How does a catalyst work in speeding up a reaction Quizizz?

A catalyst increases the effectiveness of collisions between reactants, which is how it works to speed up a reaction.

Which of the following slows down the rate of a chemical reaction Quizizz?

Chemical reactions are slower as a result of catalysts.

Why does breaking up a solid reactant increase the rate of reaction *?

Breaking the reactant into smaller pieces increases the surface and exposes more particles to the reaction mixture, increasing the frequency of collisions and, consequently, the rate of reaction. If one of the reactants is a solid, only the particles at the surface can participate in the reaction.

Why don t all collisions between particles cause a reaction Quizizz?

The reactant particles will rebound if they collide with less energy than the activation energy, and no reaction will take place.

Which factors decrease the rate of a reaction?

As a result, almost all reactions have an increase in reaction rate as temperature rises, while almost all reactions have a decrease in reaction rate as temperature falls.

What happens to the rate of reaction when you decrease the temperature of a chemical reaction?

The reaction rate decreases as the temperature drops because the molecules move more slowly and collide less.

What makes an effective collision Quizizz?

When molecules collide, when they do so in the right orientation, and when they do so with enough kinetic energy, this is what is known as an effective collision.

What causes a chemical reaction what must happen for a chemical reaction to take place?

When chemical bonds between atoms are made or broken, chemical reactions take place. The substances that initiate a chemical reaction are referred to as reactants, and the substances produced as a result of the reaction are referred to as products.
