Most of the naturally occuring processes are spontaneous.
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 )

Most of the naturally occuring processes are spontaneous. Exothermic reactions associated with a decrease in entropy are spontaneous at lower temperatures. Justify on the basis of Gibbs equation.

Why most of the exothermic processes (reactions) are spontaneous?

Most of the naturally occuring processes are spontaneous. Find the temperature above which the reaction, MgO(s) + C(s) rarr Mg(s) + CO(g) becomes spontaneous. (Given Delta_rH^@ = 490 kJ//mol and Delta_rS^@ = 198 J//molK )

In which of the following conditions, process will be spontaneous?

Assertion: An electrochemical cell can be set up only if the redox reaction is spontaneous. Reason: A reaction is spontaneous if free energy change is negative.
