Answer : The initial rate of the reaction is, 
Explanation :
First we have to calculate the rate constant of the reaction.
Expression for rate law for first order kinetics is given by :
![k=\frac{2.303}{t}\log\frac{[A_o]}{[A]}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B2.303%7D%7Bt%7D%5Clog%5Cfrac%7B%5BA_o%5D%7D%7B%5BA%5D%7D)
where,
k = rate constant = ?
t = time taken for the process = 44 s
![[A_o]](https://tex.z-dn.net/?f=%5BA_o%5D)
= initial amount or concentration of the reactant = 0.1108 M
![[A]](https://tex.z-dn.net/?f=%5BA%5D)
= amount or concentration left time 44 s = 0.0554 M
Now put all the given values in above equation, we get:
Now we have to calculate the initial rate of the reaction.
Initial rate = K [A]
At t = 0, ![[A]=[A_o]](https://tex.z-dn.net/?f=%5BA%5D%3D%5BA_o%5D)
Initial rate = 0.0157 × 0.1108 =
Therefore, the initial rate of the reaction is,
Answer:
81 molecules
Explanation:
The reaction between C5H12 and O2 is a combustion reaction and is represented by the following equation;
C5H12 + 8O2 --> 5CO2 + 6H2O
The ratio of C5H12 to O2 from the above equation is 1 : 8.
Aplying the conditins of the question; 24 molecules each of C5H12 and O2 we have;
3C5H12 + 24O2 --> 15CO2 + 18H2O
This means we have 24 - 3 = 21 molecules of C5H12 that are unreacted.
Total molecules is given as;
3(C5H12) + 24(O2) + 15(CO2) + 18(H2O) + 21(Unreacted C5H12) = 81 molecules
