For a reaction , `2A+D rarr3C`, the rate of appearance of C at time t is `1.2 xx10^(-4) "mol L"^(-1) s^(-1)` . Find the rate of reaction.

Explanation

To find the rate of reaction for the given chemical equation \(2A + D \rightarrow 3C\), we can follow these steps:

### Step 1: Understand the relationship between the rate of appearance of products and the rate of reaction.
The rate of reaction can be expressed in terms of the rate of appearance of products or the rate of disappearance of reactants. For the reaction given, we can relate the rate of appearance of \(C\) to the rate of reaction.

### Step 2: Write the expression for the rate of reaction.
The rate of reaction can be defined as:
\[
