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.

Explanation

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:

\[ [A]_0 - [A] = k \cdot t \]
