True or False. Increasing the temperature of a reaction by two, decreases the activation energy by two.

At the same temperature, two reactions with equal activation energy have rates that differ by a factor of 5. Explain

Determine the ratio of the rate constants for the following reactions at 30 ºC.

A + B → C; E_a = 100 kJ/mol
X + Y → Z; E_a = 18 kJ/mol

Assume both reactions have the same pre-exponential factor.
