(a)

Interpretation Introduction

Interpretation: Whether the given process 1 is spontaneous or non-spontaneous needs to be determined.

Concept Introduction: There are two types of the chemical reactions occurring in the environment that is spontaneous reaction and non-spontaneous reactions. Spontaneous reactions are exergonic thus, decrease in the enthalpy and increase in the entropy of the system takes place. On the other hand, the endergonic reactions are non-spontaneous.
