Question
Assertion: Atconstanttemp0ºCand1atm,the changeH2O(s)→H2O(I)DH and DE both are zero.
Reason: During is other mal process Hand E both remains constant.
- If both Assertion and Reason are true and the Reason is correct explanation of the Asser- tion.
- If both Assertion and Reason are true but Rea- son is not correct explanation of the Asser- tion.
- If Assertion is true but the Reason is false.
- If Assertion & Reason both are false
The correct answer is: If Assertion & Reason both are false
