The reaction CH3−CH2−NO2+OH−⟶CH3−CH−NO2+H2O obeys the rate law for pseudo first-order kinetics in the presence of a large excess of hydroxide ion. If 1% of nitroethane undergoes reaction in half a minute when the reactant concentration is 0.002 M. What is the pseudo-first-order rate constant? (log 99 = 1.996)

ANSWER

CH3−CH2−NO2+OH−⟶CH3−CH−NO2+H2O

Rxn in first order w.r.t CH3−CH2−NO2

∴r=R[CH3−CH2−NO2]

Rate law equation

−R×t=[CH3−CH−NO2
