Characterize a system at chemical equilibrium with respect to each of the following a. the rates of the forward and reverse reactions b. the overall composition of the reaction mixture For a general reaction3A(g)+B(g)2C(g), if one starts an experiment with only reactants present, show what the plot of concentrations of A, B, and C versus time would look like. Also sketch the plot illustrating the rate of the forward reaction and rate of the reverse reaction versus time.
