1.	Correct statements form the graph I) Above 1073K, DeltaG^(0) for the formation of Fe_(2)O_(3) is less negative than DeltaG^(0) for the formation of CO from carbon II) Above 1073K, Carbon can reduce Fe_(2)O_(3) III) Below 1073K, CO can reduce Fe_(2)O_(3)IV) In blast furnace, reduction of Fe_(2)O_(3) occurs in different temperature ranges with below 1073K by CO (or) above 1073K by carbon
Answer» Only I I, II only I, II, III only All Solution :If `DeltaG=-ve` the PROCESS is SPONTANEOUS
