Two reactions with different activation energies have the same rate at room temperature. Which statement correctly describes the rates of these two reactions at the same, higher temperature?

A) The reaction with the larger Ea will be faster.
B) The reaction with the smaller Ea will be faster.
C) The two reactions will continue to occur at the same rates.
D) A prediction cannot be made without additional information.

The book says the answer is A but that makes no sense to me. I think it is B, please help explain.

I also believe it is B. Assuming everything is the same, except T changes, then the smaller activation one will have a faster right.
