On adding Cl

ion the equilibrium will shift in the backward direction, so [CoCl

2−
will increase.
On dilution, the volume will increase which results in a decrease in concentration of [CoCl

2−
Though the amount of [Co(H

2+
will get increased but its concentration cannot get doubled as volume has increased.
As the reaction is exothermic in nature so increasing temp will shift equilibrium is a backward direction.
