an excess of H2(g)? 

N2(g) + 3 H2(g) ---> 2 NH3(g)

N2(g) + 3 H2(g) ---> 2 NH3(g)

Since the reactants and the product are all gas, they all need to satisfy PV=nRT.

And for a closed gas system P and T are certain, so we can consider V1/V2=n1/n2.

In this reaction the molar ration between NH3 and N2 is 2:1

Therefore V(NH3)/V(N2)=2:1

V(NH3)=2V(N2)=2x3.5 L=7L
