step by step answer

9. The following chemical reactions take place in a liquid-phase batch reactor of a constant volume V. A2B,r1[molA consumed/(L.s) ]=0.1CA BC,r2[molC generated /(Ls)]=0.2CB where the concentration CA and CB are in mol/L. The reactor is initially charged with pure A at a concentration of 1.00mol/L. (a) Write time-dependent mole balances on A,B and C, convert them into expressions for dtdCA, dtdCB, and dtdCC and provide initial conditions. (b) Without doing detailed calculations, sketch on a single graph the plots you would expect to obtain of CA versus t,CB versus t, and CC versus t. Clearly show the function values at t=0 and t and the curvature (concave up, concave down, or linear) in the vicinity of t=0. Briefly explain your reasoning. (c) Which of the following statements is true? A. At any moment, CA+2CB+CC=1mol/L. B. At any moment, CA+CB+CCC=1mol/L. C. At any moment, 2CA+CB+CC=2mol/L. D. At any moment, 2CA+CB+2CcC=2mol/L. (d) Solve the maximum of CB (optional)
