An increase in pressure  \n[de/in]creases the crowding of gaseous molecules. The system will respond by [de/in]creasing their crowding. Crowding is decreased in gases when [fewer/more] molecules are formed. In the Haber Process the [forward/reverse] reaction makes fewer molecules than the [forward/reverse] reaction. In the forward reaction   molecules of ammonia are made from every   molecules of reactants ( ~~ ~~ N2 and ~~ ~~ H2 molecules) . Consequently, an increase in pressure   equilibrium for a while by making the [forward/reverse] reaction occur ata higher rate than the [forward/reverse] reaction. This causes [more/less] ammonia to be formed and [more/less] nitrogen and hydrogen. After a while a new dynamic equilibrium is reached. The rates of forward and reverse reactions are again   to one another, and the amounts of reactants and products will [change/remain constant] . However, compared to before the pressure was applied, there will now be [more/less] ammonia present at equilibrium. The equilibrium constant value, Kc, however, will be [higher than/lower than/the same as] it was in the original equilibrium.  \n􀀚 CHEMICAL INDUSTRIES RESOURCE PACK 􀂈 Creative Commons BY-NC-SA  \nDecreased pressure  \nDecreasing pressure [de/in]creases the crowding of gaseous molecules.
