7. The rate constant for the hydrolysis of a m-chloro substituted and p-methoxy substituted organic substance are 0.50 and 0.015 at 25 C. respectively. The o values of m-Cl and p-OMe are +0.37 and -0.27, respectively. Calculate the reaction constant p and rate constant for hydrolysis of unsubsituted substance and p-nitro (6 = +0.75) substituted substance
