CHEMISTRY · Single correct · CBSE · Chemistry · Chemical Kinetics · Chemical Kinetics

Problem

\text{Rate}=k[\mathrm{H}^+][\text{ester}]=k'[\text{ester}]

. If the acid concentration is doubled at constant ester concentration: 1. the second-order rate constant

k

is doubled; 2. the pseudo-first-order rate constant

k'

is doubled; 3. the reaction rate is doubled. Which statements are correct? (a) 1 and 2 (b) 2 and 3 (c) 1 and 3 (d) 1, 2 and 3
