Answer to Question #169421 in Physical Chemistry for Iwuogu Juliet ifeoma

Question

Calculate the entropy change in the evaporation of 1 mole of water at 100 degree celcius .latent heat of evaporation of water is 9,650 Cal's per mole.

Answer 1

As we know,

□S = □H/T

= 9650/373

= 25.9 Cal/mole-K

Entropy change = [25.9] Cal/mol-K
