Given the reaction at equilibrium: 2 SO2(g) + O2(g) ↔ 2 SO3(g) + heat

The rate of the forward reaction can be increased by adding more SO2 because the

A) temperature will increase
B) forward reaction is endothermic
C) reaction will shift to the left
D) number of molecular collisions between reactants will increase
