Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R. Assertion A : In an Ellingham diagram, the oxidation of carbon to carbon monoxide shows a negative slope with respect to temperature. Reason R : CO tends to get decomposed at higher temperature. In the light of the above statements, choose the correct answer from the options given below.

1. (1) A is not correct but R is correct
2. (2) A is correct but R is not correct
3. (3) Both A and R are correct but R is NOT the correct explanation of A
4. (4) Both A and R are correct and R is the correct explanation of A

Correct answer: (2) A is correct but R is not correct

Solution

The assertion is correct because the negative slope in the Ellingham diagram indicates that the oxidation of carbon to carbon monoxide becomes more favorable at higher temperatures. However, the reason provided is not correct as it does not accurately explain the behavior of carbon monoxide in relation to the oxidation process.
