For the exothermic reaction 3H2(g) + N2(g) 2NH3(g) which of the following changes could be carried out in suc

Question

removing NH3 and adding H2
removing NH3 and lowering the temperature
removing NH3 and raising the temperature
removing NH3 and decreasing the volume

Answer 1

Removing NH3 and lowering the temp would push the equilibrium toward the products side of the reaction.

Adding H2 would also help.

Raising the temp would inhibit rxn progress as the rxn is exothermic.

Decreasing the volume would encourage rxn progress because the reaction equation indicates that 4 mol of gas reacting to form 2 mol of gas. This would mean that the volume wants to decrease by a factor of 2. Therefore decreasing the rxn volume would encourage rxn progress.

Answer 2

removing NH3 and lowering the temperature
