A bimolecular heterogeneous catalytic reaction: A(g) +B(g) →P showed that the rate increased linearly with
PA and then became constant as the partial pressure of A was increased. However, the rate increased linearly
with PB at all partial pressures of B. Which statement is true for this mechanism?
Both A and B reacted in the gas phase
A was adsorbed on the catalyst surface and the adsorbed A reacted with B in the gas phase
Both A and B were adsorbed on the catalytic surface and adsorbed A and B reacted
B was adsorbed on the catalyst surface and the adsorbed B reacted with A in the gas phase
