3. A gas phase reaction with stoichiometry 2A 2B + C follows second order rate law;

= 2 [mol/L.s]

k= 0.204 L/mol.s at 980 K

Suppose the reaction is carried out in a batch reactor of constant volume V(m3) at a constant temperature T (K), beginning with pure A at a concentration of CA0.

a) Write a differential balance on A and integrate it to obtain an expression for CA(t) in terms of CA0 and k.

b) Suppose the reaction is carried out at 980 K, beginning with a mixture at 1.20 atm containing 70mole% A and the balance a chemically inert gas. How long (minutes) will it take to achieve a 90% conversion of A?

c) Plot the change in concentration of A vs time.

Please dont use answer of same questions in here.. i want to different calculation.
