Question

Forward reaction goes virtually to completion when Kc is :1)positive and small 2)positive and large 3)negative and large 4)unity​

Answer 1

2 positive and large

Answer 2

2 is the answer.

REASON: If Kc is large and positive.It means forward reaction so reactants reacts almost completely.
For checking the reaction is going to completion or not calculate degree of dissociation If degree of dissociation is greater than 5% then reaction goes virtually to completion.


PLEASE MARK BRAINLIST.
IF YOU UNDERSTAND IT WELL.
