Explain spontaneity of a process in terms of Gibbs energy.

Explain the spontaneity of a process.

Most of the naturally occuring processes are spontaneous. Give the criteria for spontaneity of a process in terms of free energy change (DeltaG) .

Give the criteria for spontaneity of a process in terms of free energy change( DeltaG )

Most of the naturally occurring processes are spontaneous. a) Give the criteria for spontaneity of a process in terms of free energy change ( DeltaG ) b) Exothermic reactions associated with a decrease in entropy are sponaneous at lower temperatures. Justify on the basis of Gibbs equation. c) Find the temperature above which the reactin MgO_((s))+C_((s))rightarrow Mg_((s))+CO_((g)) becomes spontaneous. (Given ( Delta_rH^theta=490kJmol^-1 & Delta_rS^theta=198JK mol^-1 )
