Question

In the following equilibrium,
$\frac{1}{2}{N}_2\left(g\right)+O_2\left(g\right)\leftrightharpoons N{O}_2\left(g\right)+heat$

• A. the equilibrium will shift to the right due to the right due to decrease in the concentration of $N_2$
• B. the equilibrium will shift to the right due to the right due to decrease in temperature
• C. the equilibrium will shift to the due to an increase in volume
• D. the equilibrium will shift to the left due to an increase in the concentration of $O_2$

Answer 1

The correct option is A the equilibrium will shift to the right due to the right due to decrease in the concentration of $N_2$

(A) is correct option

because according to be chatelir's principle states that change in pressure, temp. or conc. is applied to system in equilibrium, the equilibrium will shift so as to tend to counteract effect of constraint
