What are the total degrees of freedom if the number of species are 8, total streams are 3, stream temperature 3, stream pressure 3 and heat released 1, extent of reaction 2?

A. 8

B. 12

C. 15

D. 17

I had been asked this question by my school teacher while I was bunking the class.

This key question is from Degrees of Freedom Analysis topic in portion Energy Balances that Include the Effects of Chemical Reaction, Ideal Processes, Efficiency and the Mechanical Energy Balance and Heats of Solution and Mixing of Basic Chemical Engineering

The correct choice is D. 17

To elaborate: Degrees of freedom = 8 + 3 + 3 + 3 + 1 + 2 = 17.
