Problem

A mixture at equilibrium for the reaction A(g) ⇌ 2 B(g) experiences a sudden injection of B at t=10 t = 10\,s that instantly doubles [B]. Immediately after the injection, [A] is unchanged. Explain which direction the reaction will proceed between 10 s and the time equilibrium is re-established, using the concept of QQ versus KK.
