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 C_A0 = 2.0 mol/dm³. 2A + B ⇄ C
a. What is the concentration of B initially? C_B0 = ____ (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 –r_A 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 C_A0 = 2.0 mol/dm³, kA = 2 dm⁶/mol²•s, and K_C = 0.5 all in proper units –r_A = ____.
e. What is the equilibrium conversion?
f. What is the rate when the conversion is
