(a)

Interpretation Introduction

Interpretation:

Mass of product (NH4Cl) produced in reaction has to be determined.

Concept Introduction:

Ideal gas law can be represented as equation for state for any imaginary gas. Expression for ideal gas equation is as follows:

  PV=nRT

Here,

P is pressure of the gas.

V is volume of gas.

n denotes moles of a gas.

R is gas constant.

T is temperature of gas.

Answer to Problem 3C.15E

Mass of product (NH4Cl) produced in reaction is 4.25×103 g.

Explanation of Solution

Balance reaction is given as follows:

  NH3(g)+HCl(g)NH4Cl(g)

The expression to calculate moles of gas is as follows:

  n=PVRT        (1)

Conversion factor to convert 30°C to Kelvin is as follows:

  T(K)=temperatureincelsius+273.15=30°C+273.15=303.15K

Conversion factor to convert 25°C to Kelvin is as follows:

  T(K)=temperatureincelsius+273.15=25°C+273.15=298.15K

Substitute 100 Torr for P, 15.0 mL for n, 62.364 LTorrK1mol1 for R and 303.15K for T in equation (1) to calculate moles of NH3 gas.

  n=((100 Torr)(15.0 mL)(62.364 LTorrK1mol1)(303.15K))(1 L103 mL)=7.9341×105 mol

Substitute 150 Torr for P, 25.0 mol for n, 62.364 LTorrK1mol1 for R and 298.15K for T in equation (1) to calculate moles of HCl gas.

  n=((150 Torr)(25.0 mL)(62.364 LTorrK1mol1)(298.15K))(1 L103 mL)=2.0116×104 mol

Since HCl gas present in excess in reaction mixture thus NH3 is a limiting reagent. Therefore, product is formed according to limiting reagent.

According to reaction, 1 mole of NH3 produced by 1 mole of NH4Cl thus 7.9341×105 mol of NH4Cl can be produced from 7.9×105 mol of NH3.

Mass of 7.9341×105 mol of NH4Cl can be calculated as follows:

  Mass(NH4Cl)=(Moles(NH4Cl))(Molar mass(NH4Cl))=(7.9341×105 mol)(53.49 g/mol)=4.25×103 g

Hence mass of product NH4Cl produced in reaction is 4.25×103 g.

(b)

Interpretation Introduction

Interpretation:

Pressure of excess gas at 27 °C after completion of reaction has to be determined.

Concept Introduction:

Ideal gas law can be represented as equation for state for any imaginary gas. Expression for ideal gas equation is as follows:

  PV=nRT

Here,

P is pressure of the gas.

V is volume of gas.

n denotes moles of a gas.

R is gas constant.

T is temperature of gas.

Answer to Problem 3C.15E

Pressure of excess gas at 27 °C after completion of reaction is 0.075atm.

Explanation of Solution

The number of moles of excess HCl(g) after reaction is completed can be calculated as follows:

  Mole(HCl)=(2.0116×104 mol)(7.9341×105 mol)=1.2181×104 mol

Total volume of mixture after the completion of reaction can be calculated as follows:

  Total Volume of reaction mixture=(25.0 mL)+(15.0 mL)=40.0 mL

The expression to calculate pressure of gas is as follows:

  P=nRTV        (2)

Conversion factor to convert 27°C to Kelvin is as follows:

  T(K)=temperatureincelsius+273.15=27°C+273.15=300.15K

Substitute 40.0 mL for V, 1.2181×104 mol for n, 62.364 LTorrK1mol1 for R and 300.15K for T in equation (1) to calculate volume of HCl gas.

  P=((1.2181×104 mol)(62.364 LTorrK1mol1)(300.15K)(40.0 mL))(103 mL1 L)=57.0068 Torr(1atm760Torr)=0.075atm

Hence pressure of excess gas at 27 °C after completion of reaction is 0.075atm.
