Consider the first-order conversion of reactant A to product B as follows: A ⟺ B. If k1 is equal to 0.16 s-1 and k2 is equal to 0.03 s-1, then what will be the velocity of the forward reaction (vf) when equilibrium is reached? Assume that the initial concentration of reactant A is 1.08 M. Recall that vf (at equilibrium) is equal to k1 times the equilibrium concentration of reactant A. Report your answer in terms of M/s to the nearest thousandth.
