Question

An increase in temperature affects the reaction rate by decreasing the velocities of particles that collide in the reaction. increasing the number of molecules that have sufficient kinetic energy to react. increasing the number of molecules that have sufficient potential energy to react. decreasing the energy that particles need to overcome the energy activation barrier.

Answer 1

Answer:

increasing the number of molecules that have sufficient kinetic energy to react.

Answer 2

An increase in temperature affects the reaction rate by;

Option B; increasing the number of molecules that have sufficient kinetic energy to react

• When we increase the temperature of a reaction, it means we are increasing the thermal energy being applied to the reaction.

• Now, this increase in thermal energy means that the kinetic energy of the molecules will increase which means they will collide more with each other and as such the molecules will have more kinetic energy to react.

• Thus, in conclusion, we can say that an increase in temperature affects the reaction rate by increasing the number of molecules that have sufficient kinetic energy to react..
