Consider the following exothermic reaction 2SO2(g) + O2(g) ↔ 2SO3(g) If the temperature of the reaction is reduced from 800°C to 500°C, an no other change takes place, then

Consider the following exothermic reaction

2SO_2(g) + O_2(g) ↔ 2SO_3(g)

If the temperature of the reaction is reduced from 800°C to 500°C, an no other change takes place, then

A the reaction rate increases
B concentration of SO₃ decreases
C concentration of SO₃ increases
D SO₂ gas becomes unreactive
E O₃ gas becomes unreactive
