Chapter 5, Problem 5.113P

(a)

Interpretation Introduction

Interpretation:

The number of blue particles and black particles is in $\text{B}$ after stops are opened and the system reaches equilibrium is to be calculated.

Concept introduction:

A reaction is said to be at equilibrium when the rate of the forward reaction becomes equal to the rate of backward reaction.

Equilibrium is the state at which no change in the amount of the substance takes place.

(c)

Interpretation Introduction

Interpretation:

The pressure in container $\text{C}$ after stopcocks are opened is to be calculated.

Concept introduction:

The expression to calculate the partial pressure of the gas is as follows:

$P_{\text{gas}}=X_{\text{gas}}\cdot P_{\text{total}}$

Here, $P_{\text{gas}}$ is the partial pressure of the gas, $X_{\text{gas}}$ mole fraction of the gas and $P_{\text{total}}$ is the total pressure.

The expression to calculate the mole fraction of the gas is as follows,

$X_{\text{gas}}=\frac{\text{Moles of gas}}{\text{Total moles}}$

Here, $X_{\text{gas}}$ is the mole fraction of the gas.
