Question

The exothermic formation of $C I F_{3}$ is represented by the equation:
$C l_{2} (g) + 3 F_{2} (g) ⇌ 2 C I F_{3} (g); △ H = - 329 k J$
Which of the following will increase the quantity of $C I F_{3}$ in an equilibrium mixture of $C l_{2}, F_{2} a n d C I F_{3}$ ?

Solution

The correct option is A By addition of $F_{2}$
The reaction given is an exothermic reaction.
number of moles of products are less than the number of moles of reactants.
According to Le - chatalier's principle lowering of temperature, addition of $F_{2}$ or $C l_{2}$ favours the forward reaction and hence the production of $C I F_{3} .$
Increasing the volume of the container, the concentration of reactancts will decrease and the reaction will shift in backward direction.
