Consider the following reaction at equilibrium: 2 NH3(g) ⇄ N2(g) + 3 H2(g) What does Le Chatelier's principle predict will happe
1 answer:
Answer : The equilibrium will shift in the left direction.
Explanation :
Le-Chatelier's principle : This principle states that if any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
The given reaction is:
As per question, when we are adding then the concentration of
is increased on product side then the equilibrium will shift in the direction where decrease of concentration of
takes place. Therefore, the equilibrium will shift in the left direction.
Thus, the equilibrium will shift in the left direction.

Answer:
The pressure in the new flask would be if the
here acts like an ideal gas.
Explanation:
Assume that the sample here acts like an ideal gas. By Boyle's Law, the pressure
of the gas should be inversely proportional to its volume
.
For example, let the initial volume and pressure of the sample be and
. The new volume
and pressure
of this sample shall satisfy the equation:
.
In this question,
- The initial volume of the gas is
.
- The initial pressure of the gas is
.
- The new volume of the gas is
.
The goal is to find the new pressure of this gas, .
Assume that this sample is indeed an ideal gas. Then the equation should still hold. Rearrange the equation to separate the unknown,
. Note: make sure that the units for
and
are the same before evaluating. That way, the unit of
.
