Complete Question
.For the simple decomposition reaction: , the rate = and k = . How long (in seconds) will it take for the concentration of AB to reach one-third of its initial concentration of ? Enter to 2 decimal places
Answer:
The time it would take would be
Explanation:
The given decomposition reaction is
Also initial concentration of AB is
The rate constant is given as
The objective of this solution is to obtain the time(t) it would take for concentration of AB to reach one third of its initial concentration
Now the the concentration at time t is
f
Now this time is mathematically represented as
substituting value
