Question
2SO₂ + O₂ → 2SO₃
Rate of formation of SO₃ according to the reaction is 1.6 × 10⁻³ kg min⁻¹. Hence rate at which SO₂ reacts is:
Solution
1. Break Down the Problem
We start with the balanced chemical reaction: We need to find the rate at which reacts given the rate of formation of .
2. Relevant Concepts
According to the stoichiometry of the reaction:
- For every 2 moles of that react, 2 moles of are produced.
- Thus, the rate of reaction for will be equal to the rate of formation of multiplied by the inverse of the stoichiometric coefficients.
3. Analysis and Detail
Let’s denote:
- Rate of formation of .
- Let the rate at which reacts be .
From the stoichiometry of the reaction: This indicates that the rate at which reacts is the same as the rate at which forms.
Therefore, we can express it as:
4. Verify and Summarize
Since the coefficient for and are equal in a one-to-one relationship based on their stoichiometric coefficients in the balanced equation, the rates are equal. Hence, no further adjustments are necessary.
Final Answer
The rate at which reacts is:
