(a)

Interpretation Introduction

Interpretation:

The balanced equation for the given reaction rate of change in concentration has to be written.

Concept introduction:

Rate of reaction: The rate of the reaction for any interval of time can be expressed as the negative of the change in concentration of reactant by the change in time or positive sign of the change in concentration of product by change in time.

$\begin{array}{l}\text{ Reaction: R}\to \text{P}\\ \\ \text{Rate}\text{of}\text{decomposition}\text{of}\text{Reactant = }\frac{\text{- change in }\left[\text{R}\right]}{\text{change in time}}\text{ = }\frac{\text{-Δ}\left[\text{R}\right]}{\text{Δt}}\\ \\ \text{Rate}\text{of}\text{formation of product = }\frac{\text{+ change in }\left[\text{P}\right]}{\text{change in time}}\text{ = }\frac{\text{-Δ}\left[\text{P}\right]}{\text{Δt}}.\end{array}$

(b)

Interpretation Introduction

Interpretation:

For the given reaction, the rate of oxygen decreasing has to be predicted.

Concept introduction:

Rate of reaction: The rate of the reaction for any interval of time can be expressed as the negative of the change in concentration of reactant by the change in time or positive sign of the change in concentration of product by change in time.

$\begin{array}{l}\text{ Reaction: R}\to \text{P}\\ \\ \text{Rate}\text{of}\text{decomposition}\text{of}\text{Reactant = }\frac{\text{- change in }\left[\text{R}\right]}{\text{change in time}}\text{ = }\frac{\text{-Δ}\left[\text{R}\right]}{\text{Δt}}\\ \\ \text{Rate}\text{of}\text{formation of product = }\frac{\text{+ change in }\left[\text{P}\right]}{\text{change in time}}\text{ = }\frac{\text{-Δ}\left[\text{P}\right]}{\text{Δt}}.\end{array}$
