Assertion : On increasing pressure there occurs a decrease in melting point of ice.
Reason : On melting ice contracts,

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct, but(R) is not the correct explanation of (A)
C. If(A) is correct, but (R) is incorrect
D. If both (A) and (R) are incorrect

Answer

A

Explanation

On increasing pressure, water-ice equilibrium shifts towards water side for the volume of the system decreases on melting of ice. For ice-water equilibrium again, temperature will have to be lowered. In other words melting point ofice decreases.
