What is the entropy change of the gas, heated in a steady-flow process at approximately atmospheric pressure when 2,500 kJ is added to 15 mol of 1- butene initially at 260ºC?

EXPERT ANSWER

The entropy change of the gas can be found using the entropy equation with the help of final temperature, which can be found using the heat transferred.

Initial temperature, T, 2 260c 533K Heat added, Q : 2500 KJ Number of moles, no is mol Heat capacity of 1- butene. at specifi

The entropy of the gas is the entropy of the system which is 1.98 KJ / mol. K.
