Answer:
K = 1.69M
Explanation:
For the reaction:
2NH₃(g) ⇄ N₂(g) + 3H₂(g)
K is defined as:
k = [N₂] [H₂]³ / [NH₃]² <em>(1)</em>
Molarity in equilibrium for each specie is:
NH₃(g): 2.0mol - 2x = 1.0mol/1L = 1M → X = 0.5mol
N₂(g): X = 0.5mol/1L = 0.5M
H₂(g): 3X = 1.5mol/1L = 1.5M
Replacing:
k = [0.5] [1.5]³ / [1]²
<em>k = 1.69M</em>
<em></em>

Answer: Increasing the concentration of a reactant or decreasing the concentration of the product.
Explanation: For the equilibrium of the reaction to shift to the left, we must decrease the concentration of a reactant or increase the concentration of the product. This is based on Le Chatelier's principle which describes the effect on the equilibrium of changes in concentration or pressure of a product or a reactant. Adding more products in a system would disturb the equilibrium thus it would cause to reestablish it by shifting the reaction to the left producing the reactants. This would also be the same when you decrease the number of reactants in the system.
Answer:
B
Explanation:
As you move down the periodic table in the carbon family, the atomic radius and ionic radius increase while electronegativity and ionization energy decrease. Atom size increases moving down the group because an additional electron shell is added.
I’m going to say the answer is most likely X because memetic energy is energy being used at that moment. Because the coaster is going fastest at X we can assume that the answer is X
