The statements are true. Both assertion ad reason are correct and reason is the correct explanation for the assertion.
Explanation:
The case of liquification of a gas depends on their inter-molecular force and attraction which in turn is measured in terms of vander waal's constant a.
Hence, higher the value of a, greater the inter-molecular force of attraction, easier the liquification.
Thus the statements are true.
Both assertion ad reason are correct and reason is the correct explanation for the assertion.
