Consider the equilibrium between N₂O₄(g) and NO₂(g).

N₂O₄(g) \( \rightleftharpoons \) 2NO₂(g)          ΔH = +58 kJ\(\,\)mol⁻¹

Which changes shift the position of equilibrium to the right?

\(\begin{array}{*{20}{l}} {{\text{I.}}}&{{\text{Increasing the temperature}}} \\ {{\text{II.}}}&{{\text{Decreasing the pressure}}} \\ {{\text{III.}}}&{{\text{Adding a catalyst}}} \end{array}\)

A.     I and II only

B.     I and III only

C.     II and III only
