Solve: Calculating the Equilibrium Constant

Question: 1 mol of nitrogen and 1 mol of hydrogen are placed in a flask and allowed to come to equilibrium with the product ammonia (NH3). At equilibrium there are .8 moles of nitrogen present. What is the Keq for the reaction?

Solution Preview

First: We need to obtain a balanced reaction:

N2 + 3H2-----------> 2NH3

I know this by lots and lots of experience, but you can see from the diatomic mnemonic, HONClBrIF, that nitrogen and hydrogen are diatomic such that 2 ammonia molecules have to ...
