1. [30] A liquid reversible elementary reaction 2AB has an equilibrium constant K (1/M) at the operating conditions. The equilibrium concentrations for A is CA0=2M,B is CB0=20M Then you double the amount of A concentration in the system (2CA0) and THEN let the system reach its equilibrium again at the same temperature and pressure, the concentrations for A and B will be CA and CB. Please calculate the ratio of CB/CB0. 2. [30] Derive the rate algebra expression for the following catalytic NO2 reduction reaction (1) NO2+3S2OS+NS(K1) (Rate Limiting Step) (2) H2+2S2HS(K2) (3) 2HS+OSH2O+3S(K3) (4) 2NSN2+2S(K4)
