Factors Affecting Rate Constant

Q.

The rate constant for a reaction depends upon each of the following, EXCEPT:

1. solvent for solutions

2. temperature

3. concentration of reactants

4. nature of reactants

Q.

Why is the rate constant important?

Q.

The value of K_c for the reaction

3O₂ (g) 2O₃ (g)

is 2.0 ×10^–50 at 25°C. If the equilibrium concentration of O₂ in air at 25°C is 1.6 ×10^–2, what is the concentration of O₃?

Q. To make sure he learnt the constant of rate constant properly, Samwell Tarly tried an experiment. He tried to vary the conditions of the reaction and see how it affected the rate constant.

He performed the following reactions
$2H_2+O_2\to 2H_{2}O$

1. He changed the temperature of the reaction
2. He changed the concentrations of the reactants
3. He replaced $O_{2}with{F}_2$
4. He used a catalyst in the reaction
