At the same conditions of pressure, volume and temperature, work done is maximum for which gas if all gases have equal masses?

Options

  1. ANH ₃
  2. BN ₂
  3. CCl ₂
  4. DH ₂ ~S

Correct answer

A. NH ₃

Step-by-step solution

When p, V and T are same and mass is also same, work done depends only upon molecular mass. W 1 M ( where, M= molecular mass ) Among the given gases, NH ₃ has lowest molecular mass, so work done is maximum for it.
