How to determine Q

Postby Andrea_Torres » Sun Mar 08, 2020 4:59 pm

In the Nernst Equation there is Q and I know that you divide one on top of the other but how do I know which is on top of the other?

Q is non-equilibrium ratio of products to reactants. So, you'll need to identify which species are the products and which ones are the reactants in the overall cell reaction.

^^^ I agree with Tyler, it depends on the reaction given. Through the reaction given you are able to determine which is the product and which is the recatant.

Yes by writing the reactions, you can figure out the products and reactants and put them in the equation.

When you write out the half reactions and add them to make the complete equation the answer will result in the reaction that you base Q off of.
