A+B <-> C+D

You mix some of A and B in a closed container and the reaction begins.

As time passes, what happens to the amounts of A & B?

As time goes on, what will happen to the rate at which A & B turn into C + D?

Was there any C & D present when the reaction first started?

As time passes, what happens to the amounts of C & D in the container?

As time goes on, what happens to the rate at which C & D turn into A & B?

When the reaction reaches equilibrium, which chemicals will be present in the container?

When the reaction reaches equilibrium, what will be true of the reaction rates?

When the reaction reaches equilibrium, what will be true about the amounts of reactants and products?

I will be happy to critique your thinking on this.
