Answer
(a) Reversible reactions can occur in either directions (left to right, producing C and D, or right to left, producing A and B).
$$aA + bB \rightleftharpoons cC + dD$$
(b) Type of equilibrium where the sum of all forces is zero. If the equilibrium is disturbed, the system will try to return to the equilibrium state.
(c) The product of the equilibrium concentrations of the products divided by the product of the equilibrium concentrations of the reactants. In each case, the concentration is raised to the power of the balance of coefficient of the compound. For the reaciton above:
$$K = \frac{[C]^c[D]^d}{[A]^a[B]^b}$$
