Problem

A chemist is choosing among three synthesis reactions at the same temperature. I. A+B⇌CK=2.8×103\text{A} + \text{B} \rightleftharpoons \text{C}\quad K = 2.8 \times 10^{3} II. D⇌E+FK=4.2×10−2\text{D} \rightleftharpoons \text{E} + \text{F}\quad K = 4.2 \times 10^{-2} III. G+H⇌IK=1.5×100\text{G} + \text{H} \rightleftharpoons \text{I}\quad K = 1.5 \times 10^{0} Under identical initial conditions, which reaction is expected to give the highest equilibrium yield of products? a) Reaction III only b) Cannot be determined from the given KK values c) Reaction I only d) Reaction II only
