Answer:
The mass of
in the container is 2.074 gram
Explanation:
Given:
Volume of
lit
Equilibrium constant 
The reaction in which
is produced
⇄ 
Here equal moles of
and
is formed.
From the formula of equilibrium constant,


M
Above value shows,

So in 2 L no. moles of
=
moles.
So mass of 0.122 mole of
is =
g
Therefore, the mass of
in the container is 2.074 gram
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.
