(a)
Interpretation:
Concept Introduction:
Molar mass can be determined using the given equation,
Ideal gas Equation:
Any gas is described by using four terms namely pressure, volume, temperature and the amount of gas. Thus combining three laws namely Boyle’s, Charles’s Law and Avogadro’s Hypothesis the following equation could be obtained. It is referred as ideal gas equation.
Here,
n is the moles of gas
P is the Pressure
V is the Volume
T is the Temperature
R is the gas constant
(a)

Explanation of Solution
Number of moles of
Number of moles present after vaporization is calculated using Ideal Gas Lew as given below,
Number of moles before and after vaporization are not equal. Hence, decomposition of
(b)
Interpretation:
Partial pressure of each of the gaseous compound has to be calculated.
Concept Introduction:
Mole fraction: Quantity which defines the number of moles of a substance in a mixture divided by the total number of moles of all substances present.
Partial pressure of a gas in the mixture of gases is the product of mole fraction of the gas and the total pressure.
(b)

Answer to Problem 118QRT
Partial pressure of each of the gaseous compound is given below,
Explanation of Solution
Total number of moles is
Initial number of moles of
Change in number of moles of reactants and products can be determined as given below,
According to Dalton’s law, the total pressure exerted by each gas in a mixture is equal to the sum of the individual partial pressure of the gases.
Mole fraction of each of the gaseous compound is calculated as follows,
Partial pressure of each of the gaseous compound is determined as follows,

The Brusselator. This hypothetical system was first proposed by a group work- ing in Brussels [see Prigogine and Lefever (1968)] in connection with spatially nonuniform chemical patterns. Because certain steps involve trimolecular reac tions, it is not a model of any real chemical system but rather a prototype that has been studied extensively. The reaction steps are A-X. B+X-Y+D. 2X+ Y-3X, X-E. 305 It is assumed that concentrations of A, B, D, and E are kept artificially con stant so that only X and Y vary with time.
