The standard state of the substance should be described. Concept introduction: The standard entropy change ( Δ S ° ) for reaction can be defined as a difference between standard molar entropies of all products and reactants. The general expression for standard entropy change for reaction is as follows: Δ S ° = S ° ( products ) − S ° ( reactants ) The unit of Δ S ° is J/K and S is J/K ⋅ mol .

Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Interpretation Introduction

Interpretation:

The standard state of the substance should be described.

Concept introduction:

The standard entropy change (ΔS°) for reaction can be defined as a difference between standard molar entropies of all products and reactants. The general expression for standard entropy change for reaction is as follows:

ΔS°=S°(products)−S°(reactants)

The unit of ΔS° is J/K and S is J/K⋅mol.

1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°? To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide. kindly show me how to solve both parts of the same long problem.
