A gas phase adsorption reaction is reaction controlling. The reaction follows Eley – Rideal mechanism, represented by A + B → R. If the product also adsorbs, which of the following rate expressions is true? |
A. | -rA = \(\frac{kP_A P_B}{1+ k_A P_A+ k_R P_R} \) |
B. | -rA = \(\frac{kP_A P_B}{(1+ k_A P_A+ k_R P_R)^2} \) |
C. | -rA = \(\frac{kP_A P_B}{1+ k_A P_A+ k_R P_R} \) |
D. | -rA = \(\frac{kP_A P_B P_R}{(1+ k_A P_A+ k_R P_R)^2} \) |
Answer» B. -rA = \(\frac{kP_A P_B}{(1+ k_A P_A+ k_R P_R)^2} \) | |
