51. The major reason an increase in temperature causes an increase in reaction rate is that (A) the activation energy changes with temperature (B) the fraction of high energy molecules increases (C) molecules collide with greater frequency (D) catalysts become more effective 52. Catalysts effectively increase reaction rate by (A) increasing the Keq (B) increasing the concentration of the reactant (C) decreasing the concentration of the products (D) lowering the activation energy requirements
