Consider the following exothermic reaction $2SO_{2(g)} + O_{2(g)} = 2SO_{3(g)}$ . If the temperature of the reaction is reduced from 800ºC to 500ºC, and no other change takes place, then

the reaction rate increases

concentration of SO₃ decreases

concentration of SO₃ increases

SO₂ gas becomes unreactive

O₂ gas becomes unreactive

Correct answer is C

reducing the temperature from 800ºc to 500ºc will favour forward reaction according to Le Chatelier's principle hence the concentration of $SO_3$ increases.
