In the reversible reaction shown below, r moles of a react with s moles of b to produce t moles of c. which equation can be used to represent the equilibrium constant for the forward reaction?

The equilibrium constant divides the products by the reactants.

So, if r+sb=t(whatever variable used here)

r & b would be your reactants & (left out variable) would be your product. The # of moles would be used as exponents.

Hope that helps!

Answer///precipitate;
