Explanation:
As we know that molecules of a gas move far away from each other because they are held by weak Vander waal forces. So, when a balloon is filled by a gas then molecules of a gas strike at its walls leading to more number of collisions.
This will also lead to more expansion of the balloon. As we know that pressure is the force exerted n per unit area of a substance or object.
Thus, more is the kinetic energy of the molecules of the gas more will be the force exerted by them. Hence, more will be the pressure exerted.
Answer:
The answer to your question is: P = 419933.5 Pa
Explanation:
Data
R = 0.287 KJ/Kg°K = 287 J/Kg°K
mass = 2 kg
T = 35 °C = 308°K
Container = 0.750 meters each side
Volume = l x l x l
= 0.750 x 0.750 x 0.750
= 0.421 m³
P = mRT / V
P = (2)(287)(308) / 0.421
P = 176792 / 0.421
P = 419933.5 Pa
The given question is incomplete, here is a complete question.
At 400 K, this Reaction has 
What Is 
at 400 K for the following reaction?
(A) 8.2 x 10⁻⁴
(B) 2.9 x 10⁻²
(C) 6.7 x 10⁻⁷
(D) 1.6 x 10⁻⁷
Answer : The correct option is, (C) 
Explanation :
The given chemical equation follows:
The equilibrium constant for the above equation, .
We need to calculate the equilibrium constant for the following equation of above chemical equation, which is:
, 
The equilibrium constant for the doubled reaction will be the square of the initial reaction.
Or, we can say that
If the equation is multiplied by a factor of '2', the equilibrium constant will be the square of the equilibrium constant of initial reaction.
The value of equilibrium constant for the following reaction is:
Hence, the value of equilibrium constant for the following reaction is,
I think the correct answer from the choices listed above is option C. The substances that do not undergo chemical change when mixed are the substances NaNO3(aq) and KI(aq). They form spectator ions. Hope this answers the question.
