An increase in temperature increases the rate of a chemical reaction because

$\begin{array}{1 1}(a)\;\text{Exothermic reactions are always favored}\\(b)\;\text{the activation energy is lower}\\(c)\;\text{the particles are more likely to have favorable collision geometry}\\(d)\;\text{a greater fraction of particles have sufficient kinetic energy}\end{array}$

Can you answer this question?

For collision to be effective,molecules should have some sufficient kinetic energy.When we increase temperature a greater fraction of particles have sufficient kinetic energy.So rate increases.
Hence (d) is the correct answer.
