The work done on the gas in taking it from D to A is

Options

  1. A-414 R
  2. B+414 R
  3. C-690 R
  4. D+690 R

Correct answer

A. -414 R

Step-by-step solution

At constant temperature (isothermal process) aligned W_ D A =n R T ( P₁ P₂ )= & 2.303 2 R 300 ( 10^5 2 10^5 ) & =2.303 600 R ( 1 2 ) & =0.693 600 R =-414 R . aligned
