Half-life of a zero order reaction is 250sec. t75% ,t100% of the react...
Explanation:
t75% of the reaction:
t100% of the reaction:
- A zero order reaction follows the rate equation of the form: Rate = k[A]^0 = k
- The rate of the reaction is constant and independent of the concentration of the reactant.
- The half-life of a zero order reaction is given by the relation: t1/2 = [A]0/2k.
- Where [A]0 is the initial concentration of the reactant and k is the rate constant.
- Given, t1/2 = 250 sec.
- Therefore, [A]0/2k = 250 sec.
- From this equation, we can find the value of k.
- k = [A]0/500 sec.
t75% of the reaction:
- t75% means the time required for the reaction to reach 75% completion.
- Let's assume that the initial concentration of the reactant is [A]0.
- After 75% completion, the concentration of the reactant will be [A] = 0.25[A]0.
- The time required for the reaction to reach this concentration can be calculated using the rate equation:
- [A] = -kt + [A]0
- t = ([A]0 - [A])/k
- Substituting the values, we get:
- t75% = ([A]0 - 0.25[A]0)/k = 0.75[A]0/k = 0.75*500 sec = 375 sec.
t100% of the reaction:
- t100% means the time required for the reaction to reach 100% completion.
- After 100% completion, the concentration of the reactant will be zero.
- The time required for the reaction to reach this concentration can be calculated using the rate equation:
- [A] = -kt + [A]0
- t = [A]0/k
- Substituting the values, we get:
- t100% = [A]0/k = 500 sec.
