For the equilibrium reaction n2o4(g) ⇀↽ 2 no2(g) taking place inside a sealed container fitted with a piston, predict the effect of raising the piston (to increase the volume of the container) on the composition of the mixture. 1. the equilibrium will shift to favor formation of no2(g). 2. there will be no effect on the composition. 3. more information is needed. 4. the equilibrium will shift to favor formation of n2o4(g).
