Question

n2o4 is 10% dissociated at a total pressure p1 and 20% dissociated at atotal pressure p2 .then ratio p1/ p2

Answer 1

Answer:

Explanation:

Solution

N2O421−α⇔2NO202α

Kp=(nNO2)2(nN2O4)×[P∑n]1

For 33% dissociation:

Kp=(2×33)267×[P1133]1

For 50% dissociation:

Kp=(2×50)250×[P2150]1

∴P1P2=133×67×(2×50)2(2×33)2×150×50=2.72
