Problem
The reaction 3A(g)⇌B(g)+2C(g) has Qc=7.5 and Kc=5.0 under certain conditions. A chemist instead considers the reaction 2B(g)+4C(g)⇌6A(g), obtained by first reversing the original reaction and then multiplying all coefficients by 2. Calculate the value of the reaction quotient Qc′ for this new reaction and predict the direction in which the system will shift (toward products, toward reactants, or no net change) when compared to its corresponding equilibrium constant.
