Question

4 mol of pcl5 are heated at constant temperature in closed container. if degree of dissociation for pcl5 is 0.5 then calculate total number of moles at equilibrium

(1)

(2)

(3)

(4)

Answer 1

"Here is the solution:

PCl5 on heating gives PCl3 and Cl2

PCl5 + ∆ ---> PCl3 + Cl2

if 50% dissociate then 2 mole each of product is form and 2 mole remain of PCl5

total is 6 moles

Explanation:

Degree of dissociation is the fraction of a mole of the reactant that underwent dissociation.

It is represented by . α = amount of substance of the reactant dissociated amount of substance of the reactant present initially. Number of moles dissociated."

Answer 2

Explanation:

hope this is help full answer is 6 moles
