For the elementary reaction 2 S O 2 g + O 2 g → 2 S O 3 g , identify the correct among the following relations

Options

  1. A- d S O 2 g d t = - d O 2 g d t
  2. B+ 1 2 d S O 3 g d t = d S O 2 g d t
  3. C+ d S O 3 g d t = - 2 d O 2 g d t
  4. D+ d S O 2 g d t = - d O 2 g d t

Correct answer

C. + d S O 3 g d t = - 2 d O 2 g d t

Step-by-step solution

The rate of the given reaction in the terms of concentrations of reactants and products is d x d t = - 1 2 d S O 2 d t = - d O 2 d t = + 1 2 d S O 3 d t ⇒ + d S O 3 d t = - 2 d O 2 d t
