Q1 5.6 The rate and extent of chemical change
Why does increasing temperature usually increase the rate of a chemical reaction?
- A greater fraction of particles has energy at or above the activation energy.
- The activation energy of every reaction falls to zero.
- Particles stop colliding and stay together for longer.
- The amount of product present before the reaction rises.
That's the free sample. The rest of the questions are available with a paid plan.
