Explanation of Zero Order Reaction
A zero order reaction is a chemical reaction in which the rate of reaction is independent of the concentration of the reactant. This means that the rate of reaction remains constant over time, regardless of the concentration of the reactant.
Calculation of Time to Complete 50% of the Reaction
In a zero order reaction, the rate of reaction is given by the equation:
Rate = k[A]0 = k
Where:
- k is the rate constant
- [A] is the concentration of the reactant
Since the rate of reaction is constant, we can use the following equation to calculate the time it will take to complete a certain percentage of the reaction:
Time = (Percentage of Reaction) / (Rate of Reaction)
Using the given information that 20 percent of the reaction completes in 10 seconds, we can calculate the rate of reaction:
Rate = (20%) / (10 sec) = 0.02 sec-1
Now, we can use the above equation to calculate the time it will take to complete 50% of the reaction:
Time = (50%) / (0.02 sec-1) = 250 sec
Therefore, it will take 250 seconds to complete 50% of the reaction.
Conclusion
The time it takes to complete a certain percentage of a zero order reaction can be calculated using the given percentage and the rate of reaction. In this case, we were able to calculate the time it will take to complete 50% of the reaction using the given information that 20% of the reaction completes in 10 seconds. This type of calculation can be useful in predicting the progress of a chemical reaction and determining the optimal conditions for the reaction to occur.
