is positive for the equation the reaction will proceed.
B
If reactant and products of two reactions are put together and net 
is –ve, the overall reaction will
is –ve, the overall reaction will
C
On increasing the temperature the value of 
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.
Text Solution
Verified by ExpertsThe correct answer is:
B
: The process of interpretation involves coupling of two reactions, getting the sum of 
and looking for its sign. Overall –ve value of 
shows that reduction of ore is possible.
