Question

If in a certain reaction the decrease in reactant concentration is 20% in 20 minutes and 40% in 40 minutes. The units of the rate constant is $mollitr{e}^{-1}mi{n}^{-1}$.
If true enter 1, else enter 0.

Answer 1

The decrease in reactant concentration is 20% in 20 minutes and 40% in 40 minutes. This indicates that the rate of the reaction is independent of the substrate concentration. This is characteristic of zero order reaction. $rate=k[A{]}^0$. Hence, the units of the rate constant
is $mollitr{e}^{-1}mi{n}^{-1}$.
