Question

two moles of ideal gas is expanded reversibly from 4atm. to 3 atm at const temperature of 300k calculate work done ( ans -332)

Answer 1

Dear Student,

◆ Answer -

W = -1435 J

● Explanation -

# Given -

n = 2 mol

P1 = 4 atm

P2 = 3 atm

T = 300 K

# Solution -

Work done is calculated as -

W = -2.303nRT.log(P1/P2)

W = -2.303 × 2 × 8.314 × 300 × log(4/3)

W = -11488 × 0.1249

W = -1435 J

Therefore, -1435 J of work is done during process.

Thanks dear...
