If the concentration of water is high enough,we can assume it is constant(the reaction is first zero-respect to water).In this case,the concentration of methyl formate in water is given by the following expression:[methyl formate]=[methyl formate](0)*e^(-Keff*t)
where [methyl formate](0) is the concentration of methyl formation at the start of the reaction,Keff is the effective constant,and t is time.
Prove that the expression above agrees with the rate law and write an expression for Keff of K=0.0233 and the concentration of water.
