V₁ = initial Volume of the balloon after it is blown up = 365 L
V₂ = new Volume of the balloon after it is taken outside = ?
T₁ = initial temperature of the balloon = 283 K
T₂ = new temperature of the balloon = 300 K
using the equation
V₁/V₂ = T₁/T₂
365/V₂ = 283/300
V₂ = 387 L
Explanation:
We will use the following equation,
(a) Now, we will calculate the value of
as follows.
= 0.377
As, the
is 0.21 (which is smaller than the value) this means that equilibrium will shift to the left
.
(b) 
= 0.1155
Here,
is smaller than
which means that the equilibrium will shift to the right.
(c)
= 0.119
Here,
is smaller than
which means that the equilibrium will shift to the right
.
(d)
= 0.21
Since, here the value of
comes out to be equal to the given value. Therefore, this reaction is at equilibrium.
(e)
= 0.36
Here,
is higher than
the reaction will shift to the left.
