The vander waals constant for O2 are a=1.59 atm L2 mol−2 and b=0.0318 L mol−1.Calculate the temperature at which O2 gas behaves,ideally for longer range of pressure.

The correct option is A 625 KThe temperature at which the gas behaves ideally for a longer range of pressure is called Boyle's temperature. Boyle's temp : Tb=aRba value and b value is given by substituting the given values we the the answer to be 625 K

Boyle's temp : $T_{b} = \frac{a}{R b}$

a value and b value is given

by substituting the given values we the the answer to be 625 K
