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
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
the reaction rate increases
concentration of SO3 decreases
concentration of SO3 increases
SO2 gas becomes unreactive
O3 gas becomes unreactive
