Answer 1

Calculate the work involved when 1 mol of an ideal gas is compressed reversibly from 1.00 bar to 5.00 bar at a constant temperature of 300 K 4.01 kJ.

Explanation:

w = - 2.303 n R T log `"P"_1/"P"_2`

So, w = - 2.303 × 1 × 8.314 × 300 log `1/5`

= - 2.303 × 8.314 × 300 (log 1 - log 5)

= - 5744.14 × (0 - 0.6990)

= 4015.15 J

= 4.01 kJ
