**Statement 1:** Increase of temperature favour the formation of NH_3 by Haber's process. **Statement 2:** Increase of pressure and addition of catalyst favour the formation of NH_3.

JEE Main Chemistry question

**Statement 1:** Increase of temperature favour the formation of by Haber's process. **Statement 2:** Increase of pressure and addition of catalyst favour the formation of .

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is TrueCorrect

Answer: (D)

Solution
