your question is incomplete. A complete question is shown in figure.
solution :- For Pseudo first order reaction, The reaction should be first order with respect to ester, when concentration of water remains constant. e.g., [H2O] remains constant.
hence, rate constant k for pseudo first order reaction is given by,
, where k = k'[H20]
here,
initial concentration, C is final concentration and t is taken time.
from above data, it is clear that, k'[H2O] is constant and is equal to 2.004 × 10^-3/min. hence, it depends on Pseudo first order reaction and we can determine k from k'[H2O]
k' × 55mol/L = 2.004 × 10^-3
so, k' = 3.64 × 10^-5 mol/L/min.
