Chapter 16: Q17P (page 729)

Express the rate of reaction in terms of the change in concentration of each of the reactants and products:
$2 D (g) + 3 E (g) + F (g) \to 2 G (g) + H (g)$
When [D] is decreasing at 0.1 mol/L.s, how fast is [H] increasing?

Short Answer

Expert verified

The rate of reaction can be represented in terms of reactant disappearance or product appearance as follows:

$reaction rate = \frac{1}{2} \frac{∆ [D]}{∆ t} = - \frac{1}{3} \frac{∆ [E]}{∆ t} = \frac{∆ [F]}{∆ t} = \frac{1}{2} \frac{∆ [G]}{∆ t} = \frac{∆ [H]}{∆ t}$

When [D] is decreasing at 0.1 mol/L.s,Thus, H is increasing at a rate of 0.05 mol/L.s.

Step by step solution

Step 1: The rate of reaction in terms of the change in concentration

Therate of reaction can be represented in terms of reactant disappearance or product appearance as follows:

$reaction rate = \frac{1}{2} \frac{∆ [D]}{∆ t} = - \frac{1}{3} \frac{∆ [E]}{∆ t} = \frac{∆ [F]}{∆ t} = \frac{1}{2} \frac{∆ [G]}{∆ t} = \frac{∆ [H]}{∆ t}$

Where, the inverse of the fraction gives the stoichiometric coefficients of the molecules.

Step 2: Determine the rate of appearance of H

One molecule of H arises for every two molecules of D that vanish. The pace at which H appears can be represented as follows:

$Rate of appearance of H = \frac{∆ [H]}{∆ t}$

Determine the rate of appearance of H:

$- \frac{1}{2} \frac{∆ [D]}{∆ t} = \frac{∆ [H]}{∆ t} \frac{∆ [H]}{∆ t} = - \frac{1}{2} \times (0.1 mol / Ls) = 0.05 mol / Ls$

Thus, H is increasing at a rate of 0.05 mol/L.s.
