Assertion : At constant temperature PV vs P plot for real gases is not a straight line.
Reason : In the curves of dihydrogen and helium, as the pressure increases the value of PV also increases.

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

B

Explanation

PV vs P plot for real gases is not a straight line because real gases do not follow ideal gas equation perfectly under all conditions.
