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.
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.
View answer and explanation
Correct option: B
A is correct but R is not correct
Option B (A is correct but R is not correct) is correct because the oxidation of carbon to carbon monoxide has a negative slope due to the increase in entropy ( is positive), and CO does not tend to decompose at higher temperatures.
