two moles of an ideal gas are allowed to expand from a volume of 10 d m 3 to 2 m 3 at 300 K against a pressure of 101.325 kPa. Calculate the work done

Question

two moles of an ideal gas are allowed to expand from a volume of 10 d m 3 to 2 m 3 at 300 K against a pressure of 101.325 kPa. Calculate the work done, – 201.6 kJ, 13.22 kJ, – 810 kJ, – 18.96 kJ

MARKS App · Accepted Answer

V 1 = 10 d m 3 = 1 0 - 2 m 3 , V 2 = 2 m 3 P = 101.325 × 1 0 3 P a w = - P Δ V w = - 101.325 × 1 0 3 1.99 = - 201.6 k J
