Question

Formation of $C l F_{3}$ from $C l_{2}$ and $F_{2}$ is an exothermic process. The equilibrium system can be represented as:
$C l_{2 (g)} + 3 F_{2} ⇌ 2 C l F_{3};$ $Δ H = - 329$ kJ
Which of the following will increase quantity of $C l F_{3}$ in the equilibrium mixture?

A

Increase in temperature, decrease in pressure, addition of

C l_{2}

Solution

The correct option is D Decrease in temperature, increase in pressure, addition of $F_{2}$
$C l_{2} + 3 F_{2} ⇌ 2 C l F_{3}; Δ H = - 329 K J$
Since it is releasing energy, it is an exothermic reaction. Exothermic reactions favours making of bonds i.e formation of $C l F_{3}$ , and the reaction proceeds towards rightside at low temperatures, high pressures and also the addition of reactants $F_{2}$
