Problem
At 350 K, the equilibrium constant for the reaction A(g)⇌2B(g) is Kc=3.2. At a particular moment the mixture has Qc=5.0 for the forward reaction as written. Without performing any numerical calculation, indicate whether the value of Qc for the reverse reaction (2B(g)⇌A(g)) is greater than, equal to, or less than the corresponding Kc for the reverse reaction, and write the correct inequality symbol (>,=, or <) between them.
