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.

Which reaction is expected to have the smallest orientation factor?

What generally occurs in a reaction if the temperature is decreased?

A) The rate constant and rate of reaction is unaffected.

B) The rate constant decreases, which results in a slower rate.

C) The rate constant increases, which results in a slower rate.

D) The rate constant decreases, which results in a faster rate.

E) The rate constant increases, which results in a faster rate.
