Question

2NO(g) + O₂ (g) ⇌ 2NO₂ (g) + heat 

In this reaction how do the following changes influence the amount of the product? 

a. Decrease in temperature

b. Increase in pressure 

c. Increase in concentration of oxygen

Answer 1

a. When the temperature is decreased, rate of forward reaction increases. Hence more products is formed. 

b. When pressure is increased, rate of forward reaction increases. Hence more product is formed. 

c. When the concentration of oxygen is increased the rate of forward reaction increases. Hence more product is formed.
