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.
