Consider the equilibrium reaction represented by the following equation: 2SO2(g) + O2(g) ⇌ 2SO3(g); ∆H = 395.7 kJmol-1 Which of the following statements about the equilibrium system is correct?
Addition of catalyst changes the equailibrium position
Decrease in pressure increase in temperature SO3
Decrease in pressure increases the equilibrium concentration of O2
Increase in temperatur favours the forward reaction
