Vedclass · Answer

(A) The formation of ozone from oxygen is an endothermic reaction,not an exothermic reaction. The correct reaction is: $3 O_2 \underset{	ext{silent electric discharge}}{ightleftharpoons} 2 O_3 ; \Delta H = +284.5 \ kJ$. Therefore,the statement $3 O_2 \underset{	ext{silent electric discharge}}{ightleftharpoons} 2 O_3 ; \Delta H = -284.5 \ kJ$ is incorrect.
