What is concentration quotient ? Write concentration quotients for the the following reactions:
` N_2O_4(g) hArr 2NO_2(g)`.

Explanation

To solve the question regarding the concentration quotient for the reaction \( N_2O_4(g) \rightleftharpoons 2NO_2(g) \), we will follow these steps:

### Step 1: Understand the Definition of Concentration Quotient
The concentration quotient, denoted as \( Q \), is defined as the ratio of the product of the concentrations of the products to the product of the concentrations of the reactants, each raised to the power of their coefficients in the balanced equation.

### Step 2: Write the Balanced Chemical Equation
The balanced chemical equation for the reaction is:
\[ N_2O_4(g) \rightleftharpoons 2NO_2(g) \]
