8. For the reaction CO+NO⇄CO2+1/2N2, mechanism is CO+S⇄CO⋅SNO+S⇄NO⋅SNO⋅S+CO⋅S→CO2⋅S+N⋅SN⋅S+N⋅S→N2+2SCO2⋅S→CO2+S If nitrogen desorption is the limiting step rAD,CO=kA,CO[PCOCv−CCO⋅S/KCO]rAD,NO=kA,NO[PNOCv−CNO⋅S/KNO]rS=kS1[CCO⋅SCNO⋅S−(CCO2⋅SCN⋅S)/KS1]rSN2=kS2[CN⋅S2−kN2PN2Cv2]rD=kCO2[CCO2⋅SKCO2−PCO2Cv] If nitrogen desorption is the limiting step, which of the following is true? A. PCOCv=Cco⋅s/KCO B. PNOCv=CNO/KNO C. CCO2⋅SCO2=PCO2Cv D. All of the above
Solution :To determine which statement is true if nitrogen desorption is the limiting step in the given mechanism, let's analyze the equations provided.
