Question
Which of the following statements is correct according to the basic concepts of thermodynamics which govern the feasibility of a metallurgical process?
A.
When the value of $$\Delta G$$ is positive for the equation $$\Delta G = \Delta H - T\Delta S,$$ the reaction will proceed.
B.
If reactants and products of two reactions are put together and net $$\Delta G$$ is $$-ve,$$ the overall reaction will occur.
C.
On increasing the temperature, the value of $$\Delta G$$ becomes $$+ve.$$
D.
Feasibility of thermal oxidation of an ore can be established by Ellingham diagram in which a straight line shows the reduction reaction will proceed.
Answer :
If reactants and products of two reactions are put together and net $$\Delta G$$ is $$-ve,$$ the overall reaction will occur.
