Explanation / Answer

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)
