Question

If for $2A_{2}B(g) \rightleftharpoons 2A_{2}(g) + B_{2}(g),$
$K_{p} =$ Total Pressure (at equilibrium) and starting the dissociation from $4$ mol of $A_{2}B$ then

• A. degree of dissociation of $A_{2}B$ will be $(2/3)$
• B. total no. of moles at equilibrium will be $(14/3)$
• C. at equilibrium the no. of moles of $A_{2}B$ is not equal to the no. of moles of $B_{2}$
• D. at equilibrium the no. of moles of $A_{2}B$ is equal to the no. of moles of $A_{2}$

Answer 1

Answer: (A)

Correct answer is (a) degree of dissociation of $A_{2}B$ will be $(2/3)$
