The decomposition of NH, on platinum surface is zero order reaction. If rate constant (k) is `4xx10^(-3) Ms^(-1)`, how long will it take to reduce the initial concentration of `NH_(3)` from 0.1 M to 0.064 M.

Text Solution

AI Generated Solution

To solve the problem step by step, we will use the formula for a zero-order reaction. ### Step 1: Understand the Zero-Order Reaction For a zero-order reaction, the rate of reaction is constant and does not depend on the concentration of the reactants. The formula for a zero-order reaction is: \[ [A]_0 - [A] = k \cdot t \] ...
