Thermochemistry

Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that …

Exergonic Reaction

The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energ…

Question

Chapter 9, Problem 9.21P

Interpretation Introduction

Interpretation:

Whether ΔSo for the reaction is likely to be positive or negative needs to be explained.

Concept introduction:

The entropy is defined as randomness in the system. For a system with more gaseous species, the randomness is more as compared to liquid and solid species.
