Consider the following elementary gas-phase reversible reaction to be carried out isothermally with no pressure drop and for an equal molar feed of A and B with CA0 = 2.0 mol/dm3.(a) What is the concentration of B initially? CB0 = (mol/dm3)(b) What is the limiting reactant? (c) What is the exit concentration of B when the conversion of A is 25%? CB = (mol/dm3)(d) Write –rA solely as a function of conversion (i. e., evaluating all symbols) when the reaction is an elementary, reversible, gas-phase, isothermal reaction with no pressure drop with an equal molar feed and with CA0 = 2.0 mol/dm3, kA = 2dm6/mol2·s, and KC = 0.5 all in proper units –rA = .(e) What is the equilibrium conversion?(f) What is the rate when the conversion is:(1) 0%?(2) 50%?(3) 0.99 Xe?
