For the system
H2(g) + CO2(g) <---> H2O(g) + CO(g)
at equilibrium, the addition of H2(g) would cause (according to LeChatelier’s principle)
1. more H2O(g) and CO(g) to form.
2. only more CO2(g) to form.
3. only more H2O(g) to form.
4. no change in amounts of products or reactants.
5. only more CO(g) to form.

Adding more H2 means the reaction will shift to use the added H2 which means it will shift to the right. If it shifts to the right more H2O and more CO will form.
