Question

For n moles of an ideal gas at constant pressure, a plot of log V vs log T ( V in litre, T in kelvin) has an intercept on the log V axis equal to log ( n R / P ). For 5 moles of gas at a constant pressure of 0.1642 atm ( R = 0.0821 L atm/mol K), find the intercept. (log 2 = 0.30) Give the answer correct to two decimal places.

TestHub · Accepted Answer

V = n RT / P , so log V = log T + log ( n R / P ). n R / P = 5 x 0.0821/0.1642 = 2.5. log 2.5 = log (10/4) = 1 - 2 x 0.30 = 0.40. The intercept is 0.40. Answer: 0.40.
