Question

= 0.0062 atm, PN2 = 0.51 atm, Pan,-0.18 atm pN b) PNO = 0.012 atm, PN2-0.11 atm, 2.0 atm c) PNO = 0.0078 atm, PN2 0.36 atm, P2 = 0.67 atm 11) Two groups are measuring the kinetics of the gas phase reaction 4 PH3(g) 4g)+ Group A defines the rate as-d[PHs]dt, obtaining rate kIPHa]. Group B measures hydrogen and reports rate d[H2]dt k[PHs]. Do they report the same values? If not, how are the reported values related?

Explanation / Answer

The rate is equation by

Rate = - ( 1/4) d[PH3] / dt = ( 1/6) d[H2] /dt

Thus - d[PH3] /dt = ( 4/6) d[H2] /dt = ( 2/3) d[H2] /dt

Thus the measured value of d[H2] /dt is ( 2/3) times of - d[PH3] /dt
