A certain gaseous mixture is composed of the following: 30 mol A, 50 mol B, and 40 mol C. The mixture was heated from 30 ⁰C to 90 ⁰C at constant pressure. Specific heat capacity at constant pressure of the components of the mixture is as follows:


Cp of A = 150 J/mol-K
Cp of B = 50 J/mol-K
Cp of C = 100 J/mol-K


Determine the change in entropy in kJ/K.
