(a)
Interpretation: The grams of sucrose that decompose in the first 30 minutes are to be calculated.
Concept Introduction: The rate is a method for determining how much something changes over a predetermined period of time. The amount of reactant or product that changes per unit of time is the reaction rate.
(a)

Answer to Problem 109A
The grams of sucrose that decompose in the first 30 minutes are
Explanation of Solution
Mass of sucrose before decomposition is
In 30 minutes, the mass of sucrose goes from
The mass of sucrose that is decomposed in first 30 minutes is given as
(b)
Interpretation: The grams of sucrose decompose in the interval between 90 minutes and 120 minutes are to be calculated.
Concept Introduction: The rate is a method for determining how much something changes over a predetermined period of time. The amount of reactant or product that changes per unit of time is the reaction rate.
(b)

Answer to Problem 109A
The grams of sucrose decompose in the interval between 90 minutes and 120 minutes are
Explanation of Solution
According to the graph, the mass of sucrose in 90 minutes is
The mass of sucrose in 120 minutes is
The mass of sucrose that is decomposed between 90 minutes and 120 minutes is given as
(c)
Interpretation: The rate of decomposition with time is to be explained.
Concept Introduction: The rate is a method for determining how much something changes over a predetermined period of time. The amount of reactant or product that changes per unit of time is the reaction rate.
(c)

Answer to Problem 109A
The rate of decomposition with time is decreased.
Explanation of Solution
From the graph, the range of rate and time can be interpreted.
As the mass of sucrose is decomposed over time, it means that there is a gradual decrease in rate.
As time increases, the rate decreases.
The rate gets decreased as the decomposition occurs over time.
