For the exothermic reaction 3H2(g) + N2(g) 2NH3(g) what is the effect of doubling the volume of the reaction?

Question

the reaction will shift left to right
the reaction will shift right to left
there will be no further reaction
what happens depends on the temperature

Answer 1

doubling the volume will not affect the rxn because when you increase the volume, the rxn will favor those who have more number of molecules. in this case, since both sides have three molecules, there will be no shift in the rxn with respect to the volume...

Answer 2

Doubling the volume will cause the reaction to try to increase the number of molecules, ie move to the left.
