Catalyst

Q. A certain catalyzed reaction is known to have an activation energy Ea = 21.0 kJ/moL. Furthermore, the rate of this reaction is measured at 310. K and found to be 2.9 x 10^5 M/s. Use this information to answer the questions in the table below. Suppose the concentrations of all reactants is kept the same, but the catalyst is removed, which has the effect of raising the activation energy by 10%, from 21.0 kJ/mol to 23.1 kJ/mol. How will the rate of the reaction change?
