If an enzyme increases the rate of the hydrolysis reaction by a factor of 1 million, how much lower must the activation energy barrier be when sucrose is involved?

If an enzyme increases the rate of the hydrolysis reaction of sucrose into glucose and fructose by a factor of 7 million, how much lower must the activation barrier be?

The activation energy for the reaction NO2(g) + CO(g) → NO(g) + CO2(g) is Ea = 100 kJ/mol and the change in enthalpy for the reaction is ΔH = -250 kJ/mol. What is the activation energy for the reverse reaction?

The activation energy of a reaction is 3.5 kJ/mol and the change in enthalpy for the forward reaction is -67.2 kJ/mol. What is the activation energy of the reverse reaction?
