Question

Which of the following will increase the rate of a reaction?

Question 11 options:
A)
increasing the concentration of a reactant
B)
adding a catalyst
C)
ensuring that the reactants are properly aligned when they collide
D)
increasing the temperature
E)
All of these changes will increase the rate of a reac

Answer 1

Answer: E

Step-by-step explanation:

A higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

A catalyst increases the rate of reaction by lowering the activation energy.

An increase in temperature will raise the average kinetic energy of the reactant molecules.

The more frequently they collide, the faster the rate of reaction.

Therefore, all of these changes will increase the reaction rate.
