Chapter 5, Problem 137AE

(a)

Interpretation Introduction

Interpretation:Balanced equation corresponding to formation of hydrogen cyanide gas should be written.

Concept introduction:To balance an equation, one starts with the most complex chemical formula and then places the appropriate coefficient so as to make the stoichiometric coefficient equal on each side as per law of conservation of mass.

(b)

Interpretation Introduction

Interpretation Mass of $\text{HCN}$ produced per second is to be calculated.

Concept introduction: The expression to determine number of moles is as follows:

  $\text{Number of moles}=\frac{\text{Given Mass}}{\text{Molar mass}}$

The formula to calculate moles as per ideal gas law is as follows:

  $n=\frac{PV}{RT}$

Where,

• $R$ is gas constant.
• $V$ denotes the volume.
• $n$ denotes number of moles.
• $T$ denotes temperature.
• $P$ denotes pressure.
