For the reaction equilibrium; 2NOBr(g)⇌2NOg+Br2(g), if PBr2=P9 at equilibrium and 'P' is total pressure, the ratio is equal to:
1/81
For the reaction 2NOBr(g)⇌2NOg+Br2(g)
If PBr2=P9 then PNO=2P9
(∴NO. of moles NO=twice the no. of moles of Br2)
PNOBr=P−(PNO+PBr2)=P−(2p9+P9)=2P3
KP=P2NO×PBr2P2NOBr=(2P9)2×P9(2P3)2;KPP=181
