Chemistry 102: Kinetics: Rate Law

Question

Remember to use square brackets to show concentration. Do not include multiplication symbols in the rate equation. Do not place spaces in your answer.

Write the rate law for the following reaction, which represents an elementary step in a reaction. Your rate law should not include the states of matter.

Pt 1. SO2​Cl2​(g)SO2​(g)+Cl2​(g)

Pt 2. NO2​(g)+CO(g)NO(g)+CO2​(g)

Pt 3. 2NO2​(g)NO3​(g)+NO(g)

Answer 1

If these are elementary steps in an overall reaction, then the rate laws can be written as follows:

1). rate = k[SO₂Cl₂]

2). rate = k[NO₂][CO]

3). rate = k[NO₂]²
