Delta G^(@)vs T plot in theEllingham's diagram slopes downward for thereaction

Answer»

` Mg +(1)/(2) O_2toMg O `
` 2Ag +(1)/(2) O_2toAg_ 2O `
` C +(1)/(2)O_2 to CO`
` CO+ (1)/(2) O_2 toCO_ 2`

Solution :Forthereaction,
` C + 1//2O_ 2toCO`,the` Delta S `INCREASES. Therefore,as thetemperatureincreases ` T Delta S `increases andhence `Delta G(Delta H -T Delta S) `decreases. Inother WORDS,the SLOPE ofthecurveforformation of CO decreases. However, FORALL otheroxides, itincreases.
