The relation between rate and time is inverse relationship.
Rate = 1/ time
Let initial rate = R1
Final rate = R2 = 106 X R1
initial time taken = 10 minutes
R1/R2 = (time)2/ (time)1
Time taken for second reaction with catalyst = (R1 X time taken in first reaction) / (R2) = R1 X 10 / 106 X R1 = 10-5 minutes

Suppose that, in the absence of a catalyst, a certain biochemical reaction occurs x times per second at normal body temperature (37 °C). In order to be physiologically useful, the reaction needs to occur 2000 times faster than when it is uncatalyzed. Part A By how many kJ/mol must an enzyme lower the activation energy of the reaction to make it useful? Express your answer using two significant figures. PO AQ * o o ? Ea – Eac = kJ/mol
