Question

The exothermic formation of ClF₃ is represented by the equation:

\[\ce{Cl2(g) + 3F2(g) <=> 2ClF3(g)}\]; ΔH = −329 kJ

Which of the following will increase the quantity of ClF₃ in an equilibrium mixture of Cl₂, F₂ and ClF₃?

Options

• Adding F₂.

• Increasing the volume of the container.

• Removing Cl₂.

• Increasing the temperature.

Answer 1

Adding F₂.

Explanation:

The reaction given is an exothermic reaction thus accordingly to Le-Chatelier's principle lowering of temperature, the addition of F₂ and/or Cl₂ favour the forward direction or the production of ClF₃.
