Answer:
The concentration of methyl isonitrile will become 15% of the initial value after 10.31 hrs.
Explanation:
As the data the rate constant is not given in this description, However from observing the complete question the rate constant is given as a rate constant of 5.11x10-5s-1 at 472k .
Now the ratio of two concentrations is given as
Here C/C_0 is the ratio of concentration which is given as 15% or 0.15.
k is the rate constant which is given as
So time t is given as
So the concentration will become 15% of the initial value after 10.31 hrs.
Answer:
0.1056 mole
Explanation:
As Sally knows that the charge on the metal ion is n = +2
In that compartment
The volume of the taken in that compartment = 6.380 mL
So, the number of moles of
= 52.82 m mol
= 0.05280 mol
But n = 2
Therefore, moles of = 2 x moles of
= 2 x 0.05282
= 0.1056 mole
