Question

When the equilibrium expression is written for the reaction N₂(g)+ 3F₂(g) 2NF₃(g) What is the exponent of the concentration of fluorine,F₂?

Quizplus · Accepted Answer

The balanced equation shows that 3 moles of F₂ react to form 2 moles of NF₃. Therefore, the concentration (or partial pressure) of F₂ appears in the equilibrium expression raised to the third power, as it is raised to the power of the stoichiometric coefficient of F₂ in the balanced equation.
