When titanium(III) chloride is heated, it undergoes the following reaction:
 $2TiC{l}_3\left(s\right)\rightleftharpoons TiC{l}_2\left(s\right)+TiC{l}_4\left(g\right)$
A graph showing how K varies with temperature for this reaction is plotted below.
 

Select the correct options about the reversible reaction.

Enthalpy of the reaction under standard conditions is + 155.9 kJ mol^–1

Standard free energy change of reaction decreases with increase in temperature if Standard enthalpy change of reaction and standard entropy change of reaction are considered to be constant for given temperature interval 

Heating the equilibrium mixture after addition of inert gas at constant volume can’t effect the equilibrium composition

Standard entropy of reaction is equal to Standard enthalpy of reaction at equilibrium
