Change on Same Side

Postby Rita Chen 1B » Tue Jan 14, 2020 1:29 pm

In something like N2 + 3H2 —> 2NH3, if we increased N2, does it affect H2 as well?

Yes, increasing N2 does affect H2 as well. To restore N2 to its equilibrium concentration, the reaction would shift to the right and favor product formation. As a result, more H2 would be used up and its concentration would decrease.

If you increase N2, then H2 will decrease because the reaction will move toward the right.

It affects it by making the products more favorable, using up more H2.

If we add N2, then NH3 would increase since the rxn wants to maintain its equilibrium state. In order to make NH3, you need both N2 and H2 so your H2 concentration would decrease as the result.

If you increase N2, the increase in reactants would shift it toward the products meaning it would make more product. If you were to make more products, you need both the reactants to make it, H2 would also have to decrease.

Yes, it would decrease the [H2]. Because you increased the reactants, the forward reaction would be favored. In order for the forward reaction to occur, H2 will be used.
