Posted the answer to problem 4 and problem 5, please post multple question to get the problem 6
Q4)
For the first order reaction
ln(Ao/At) = kt
k = 0.46 s^(-1)
t = 0.20 minutes = 0.20 min * 60 sec/1min = 12 sec
Hence substituting the values we get
ln(Ao/At) = 0.46 * 12
ln(Ao/At) = 5.52
At = Ao * e^(-5.52) = 1.201 * 10^(-4) M
Therefore the concentration of CH3NC after 0.20 minutes will be 1.201 * 10^(-4) M
Q5)
Half-life of first order reaction = ln2/k
Half-life of decay = 5715 years
k = ln2/(5715 yrs) = 1.2128 * 10^(-4) yr^(-1)
