12. The reaction 2 H2S(g) + 3 02(g) 2 2 SO2(g) + 2 H2O(g) does not occur at room temperature. But it is very fast at higher temperatures. Why does raising the temperature increase the speed of a reaction? A. Raising the temperature dramatically increases the fraction of molecular collisions that have a kinetic energy greater than the activation energy. B. At higher temperatures the concentrations of the molecules are higher and they collide with each other more frequently. C. Raising the temperature lowers the activation energy. D. At higher temperatures the molecules move faster and collide with each other more frequently.
