APFIVE Effect Of A Noble Gas On Equilibrium
For the equilibrium reaction $$\mathrm{2NH_3(g)} \rightleftharpoons \mathrm{N_2(g)} + 3*\mathrm{H_2(g)}$$, what is the effect of adding a noble gas under (i) constant pressure conditions and (ii) constant volume conditions?
A
At constant pressure, the equilibrium remains unchanged; at constant volume, there is a shift to the left.
B
At constant pressure, the equilibrium shifts to the right; at constant volume, there is no shift.
C
At constant pressure, the equilibrium shifts to the left; at constant volume, the equilibrium shifts to the right.
D
The addition of a noble gas has no effect under either condition.
