Entropy change of the reaction, H2O(liquid) ⇒ H2O(gas), is termed as the enthalpy of
A. Solution
B. Vaporisation
C. Formation
D. Formation
Answer: Option B
Solution(By Examveda Team)
$$A.$$ solid ⟹ liquid → melting$$B.$$ liquid ⟹ vapor → vaporization
$$C.$$ solid ⟹ vapor → sublimation
So, enthalpy change for the reaction $${H_2}O\left( {liq} \right) \Rightarrow {H_2}O\left( {gas} \right)$$ is enthalpy change of vaporization.
In the question entropy should be replaced by enthalpy.
