Q1b: A closed tank with a volume of V = 1 mis initially filled up with there components, A, B and C. The initial concentrations are CA = 5 mol m-3, CB = 0.5 mol m-3 and Co 0.1 mol m-3 The reactions A + B and B C occur within the tanks. The generation and consumption of the components in a function of the concentration are listed in the following table: CA Generation (mol m-'-') Consumption (molm- s-") 0 0.1CA 0.1CA 0.5 CB CB 0.5 0 (a) Write the mass balance equation for each component and show that the change rate of total mass in the closed tank is equal to zero
