Chapter 1, Problem 10E

(a)

Summary Introduction

To determine: Is the reaction with ΔH=15 kJ and ΔS=15 J K^-1 spontaneous at 10 °C.

Introduction: A spontaneous reaction may include the increase or decrease in the enthalpy and entropy. The entropy is based on the concept that is in the isolated system, where everything in nature tends to move from order to disorder. It is a state of randomness in matter. The enthalpy is the internal energy in a system. The spontaneity of a reaction is assessed by the free energy changes.
