1.	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 = \(\frac{kP_A P_B}{(1+ k_A P_A+ k_R P_R)^2} \)
