Question
Two gases A and B, one being the dimer of the other, are at equilibrium. Decreasing of pressure at constant temperature or increasing of temperature at constant pressure favours the formation of more of B. The reaction could not be represented by
Options
A.2A$\rightleftharpoons$B + q calories
B.2A$\rightleftharpoons$B – q calories
C.2B$\rightleftharpoons$A – q calories
D.2B$\rightleftharpoons$A + q calories
Solution
Decrease in pressure favors the reaction is the direction of increase in moles of gas and hence, B should be monomer.
