Nitric acid basically reacts with copper as per to the reaction given 4 HNO3(l) + Cu(s) -----> Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O(l).
<h3>What is a balanced reaction?</h3>A balanced reaction includes the same number of elements on both sides of the equation.
In a chemical reaction, the stoichiometric coefficient is the number written in front of atoms, ions, and molecules to balance the number of each element between the reactant and product sides of the equation.
The balanced reaction for reaction between copper metal and nitric acid to produce copper II nitrate, nitrogen dioxide, and water will be as follows:
Thus, the above mentioned is the balanced reaction for the given scenario.

Answer:
1) The correct answer is option b.
2) The correct answer is option a.
Explanation:
1)
At 300 K, the value of the
The and
is related by :
where,
= equilibrium constant at constant pressure
= equilibrium concentration constant
R = gas constant = 0.0821 L⋅atm/(K⋅mol)
T = temperature = 300 K
= change in the number of moles of gas = 1 - 2 = -1
Now put all the given values in the above relation, we get:
The of the reaction = 24.63
Given = [X] = [Y] = [Z] = 1.0 M
Value of reaction quotient = Q
, the equilibrium will move in forward direction that is in the right direction.
2)
At 300 K, the value of the
Given =
Value of reaction quotient in terms of partial pressure =
the equilibrium will move in backword direction that is in the left direction.
