Give the units of van der Waals’ constant 'a' and 'b'.

Give the significance of van der Waals’ constant 'a' and 'b'.

Give the units of zero order rate constant.

In van der Waal's gas equation: [p + a/(v^2) ] (V-b) = RT ,Calculate the dimensions of van der Waal's constant a.

Given the unit of second order rate constant

1 mole of a diatomic gas present in 10 L vessel at certain temperature exert a pressure of 0.96 atm. Under similar conditions an ideal gas exerted 1.0 atm pressure. If volume of gas molecule is negligible, then find the value of van der Waals' constant ''a'' (in atm L^(2)//mol^(2) ).

Give the unit of third order rate constant.

Give the unit of third order rate constant.

Given the unit of firt order rate constant.

Assertion: The value of van der Waals constant a is larger for ammonia than for nitrogen. Reason: Hydrogen bonding is present in ammonia.
