Chapter 15, Problem 15.127QP

Interpretation Introduction

Interpretation:

The different equilibrium terms (color changes, pressure, molar mass, density and volume) are should be identified given sealed bulb ( ${\text{N}}_{\text{2}}{\text{O}}_{\text{4}}$ into ${\text{NO}}_{\text{2}}$) conversion reactions.

Concept Introduction:

Chemical equilibrium reaction: The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved; the concentrations of reactant and products become constant.

Equilibrium pressure: The equilibrium constant calculated from the partial pressures of a reaction equation. It is used to express the relationship between product pressures and reactant pressures. It is unites number, although it relates the pressures.

Temperature affect in equilibrium: This process chemical shifts changes (or) towards the product or reactant, which can be determined by studying the reaction and deciding whether it is exothermic or endothermic.

Kp and Kc: This equilibrium constants of gaseous mixtures, these difference between the two constants is that Kc is defined by molar concentrations, whereas Kp is defined by the partial pressures of the gasses inside a closed system.

Homogeneous equilibrium: A homogeneous equilibrium involved has a everything present in the same phase and same conditions, for example reactions where everything is a gas, or liquid everything is present in the same solution.
