(a)
Interpretation:
The average rate of consumption of hydrogen is to be determined.
Concept Introduction:
The average rate of the reaction is referred to the change in the molar concentration in the distinct interval of time. Mathematically the ratio of change in molar concentration of a reactant or a product to the change in the time interval gives the average
The average rate of consumption or the disappearance of reactant is negative. Mathematical expression is shown below.
The average rate of formation or the appearance of reactant is positive. Mathematical expression is shown below.
(b)
Interpretation:
The unique rate of reaction is to be determined.
Concept Introduction:
The unique rate of reaction is regardless of the reactant and products. It does depend upon the coefficient of the species in the balanced
