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’) capital delta S to the power of 0 end exponent=0 & capital delta G to the power of 0 end exponentremains nearly same, i.e it is independent of temperature
III) In the second reaction, (formation of CO) , there is increase in entropy & capital delta S to the power of 0 end exponent=+ve&blank capital delta G to the power of 0 end exponent becomes more –ve with increase in temperature
IV) In third reaction (formation of CO2 from CO), there is a decrease in entropy capital delta S to the power of 0 end exponent=-ve & capital delta G to the power of 0 end exponent becomes less –ve with increase in temperature
