If for `2A_2B(g) hArr 2A_2(g)+B_2(g), K_p`=TOTAL PRESSURE (at equilibrium ) and starting the dissociation from 4 mol of `A_2B` then:
A. degree of dissociation of `A_2B` will be (2/3)
B. total no of moles at equilibrium will be (14/3)
C. at equilibrium the no of moles of `A_2B` are not equal to the no of moles of `B_2`
D. at equilibrium the no of moles of `A_2B` are equal to the no of moles of `A_2`
