# Equilibria Question help watch

1. Basically, when you are working out Kc concentration for products, you do initial moles + moles reacted when given an equilibrium concentration for a reactant, for example.

So if a reactant was 1 mole intially, but 0.3 at equilbrium and you were finding out the equilibrium moles for product, would it be (0+0.3) or (0+0.7) ?
Im getting confused.

Thanks

Assuming a reaction like A <-> B, i.e. 1 mol of reactant turns into 1 mol of product.

So if a reactant was 1 mole intially, but 0 at equilbrium and you were finding out the equilibrium moles for product, would it be (0+0) or (0+1.0) ?
I hope you now know which of your suggestions was correct.

It would be (1.0 + 0.0) ?
It would be (1.0 + 0.0) ?
So, what would the amount of product formed be in your hypothetical problem?

(0+0.7) would be moles reacted + initial moles. So this the answer?
(0+0.7) would be moles reacted + initial moles. So this the answer?
