Calculating Q in cell diagram

Postby Jack Papciak 2F » Fri Mar 16, 2018 11:39 pm

In some problems, Q is calculated as products/reactants while in other problems, it is calculated as anode/cathode. As a general rule, how do you calculate Q? Is it based on the type of problem?

A question similar to this was asked years ago in Chemistry Community and so I'll put this here in hopes it helps you:

" Q comes from the equilibrium, that is, Q is the equilibrium quotient corresponding to the nonstandard conditions. Just like Q in other chemical reactions, Q is the ratio of the concentrations of reactants and products. Therefore, you can determine Q based on the overall balanced reaction. "

As for knowing when to choose what method for Q, I think you're right in that it's probably based on the type of problem but not 100% positive so please correct me if I am wrong Admins.
