The spontaneity of a process is expressed in terms of a change in Gibbs energy.
How is it useful in predicting the feasibility of a process?

The spontaneity of a process is expressed in terms of a change in Gibbs energy. How is it related to the enthalpy and entropy of a system?

The spontaneity of a process is expressed in terms of a change in Gibbs energy. a) What is meant by a change in Gibbs energy of a system? b) How is it related to the enthalpy and entropy of a system? c) How is it useful in predicting the feasibility of a process?

What is meant by a change in Gibbs energy of a system?

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

Mond's process is used for

In a reversible process the total change in entropy is DeltaS (universe) is

Entropy is a measure of the disorder of an isolated system. How is it useful in predicting whether a process is spontaneous, non-spontaneous or in equilibrium?

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 )

Deacon's process is used for the manufacture of:

What is meant by spontaneous processes? Give the criterion of spontaneity in
