The change in Gibbs free energy of the system alone provides a criterion for the spontaneity of a process at constant temperature and pressure. A change in the free energy of a system at constant temperature and pressure will be : DeltaG_("system")=DeltaH_("system")-T DeltaS_(system") For a system in equilibrium, DeltaG=0 , under conditions of contant....

Assertion : The condition of equilibrium for a rigid body is Translational equilibrium Sigma F=0 and Rotational equilibrium Sigma tau=0 Reason : A rigid body musy be in equilibrium under the action of two equal and opposite forces.

Assertion (A) : Chemical equilibrium represents a state of a reversible reaction in which measurable properties of the system ( pressure, concentration , colour etc.) become constant under the given set conditions. Reason (R ) : A chemical equilibrium is attained when the concentrations of the reactants become equal to the concentrations of the products.
