Question

How is the reaction rate affected by a temperature decrease?A. The rate increases because the reactant particle collisions are more effective.B. The rate decreases because the reactant particles collide less often.C. The rate increases because the equilibrium constant increases.D. The rate decreases because the equilibrium constant decreases.

Answer 1

1) Reaction rate. This refers to the speed of a reaction. It can be affected by concentration, pressure, temperature, surface area, and catalysts.

Increasing the temperature increases the kinetic energy of the molecules. This increases the frequency of particle collisions. If particles have more kinetic energy, collisions are more effective.

Option A.
