For a real gas 'X'the Boyle point is `240^@C`. If the van der Waals constant 'b'is `0.08 dm^3 mol^(-1)`, calculate the value of constant 'a'for 'X'.

Text Solution

Verified by Experts

The Boyle point, `T_(b)` is given as `T_(b) = (a)/(Rb)`
van der Waals. constant .a. for the gas .X. ` = T_(b) xx R xx b = 513 xx 0.0821 xx 0.08 = 3.37` atm `L^(2)mol^(-2)`.
