Question

In the gaseous reaction 2A+B->A^2B G=1200cal at 227C What total
pressure would be necessary to produce 60% conversion of B into A2B
when 2:1 mixture is used

Dear Student,

∆G=-RTln Kpor, Kp = e-∆GRT           = e-12001
987×500           =3
35 atm-2For the given reaction, Kp= nA2BnA2
 nB(P∑n)-2If initially there were 2 mol A and 1 mol B, then as 60% of b is converted, so at eqm
 nB=(1-0 6)=0 4nA = 2-1 2=0 8nA2B = 0
6So, ∑n = 1 8Hence, 2 25=(0 6)(0 8)2(0
4)(P1 8)-2 = 4 22P2or, P = 1 505 atm

In the gaseous reaction 2A+B->A^2B G=1200cal at 227C. What total pressure would be necessary to produce 60% conversion of B into A2B when 2:1 mixture is used
