Correct statement(s) regarding the graph
I) Above 983K, Carbon can reduce any metal oxide at high temperature and itself oxidised to CO
II) In the first reaction (Formation of CO2 from ‘C’) 
=0 & remains nearly same, i.e it is independent of temperature
III) In the second reaction, (formation of CO) , there is increase in entropy & =+ve&
becomes more –ve with increase in temperature
IV) In third reaction (formation of CO2 from CO), there is a decrease in entropy =-ve & becomes less –ve with increase in temperature
