The elementary gas reaction

2A + B >xC

Is carried out in a isothermal continuous reactor with no pressure drop. The feed is equal molar in A and B,and the entering concentration of A is O.5 mol/dm?.

(A) Identify the limiting reagent

(B) Plot concentration of A, B and C as a function of conversion (X = 0, 0.25, 0.5, 0.75 and 0.95)

(C) Write -rA solely as function of conversion when the reaction is an elementary , irreversible, gas-phase,

isothermal reaction with no pressure drop with an equal molar feed and with CA0= Y mol/dm at kA= 2 dm/mol. S

(D ) Plot "Levenspiel graph" (FAO= X.Y mol/s) and which reactor scheme do you suggest for 90 % conversion and why ?
