Consider the equilibrium reaction represented by the equation: 2SO2(g) + O2(g) ⇌ 2SO3(g) ∆H = - 197 kJmol-1. At equilibrium, increase in the total pressure of the system brings about
decrease in rate of the reaction of the system
decrease in temperature of the system
increase in temperature of SO3
increase in concentration of SO2
