Answer:
- <u>Decreasing the temperature of the system will shift the reaction rightward.</u>
Explanation:
The complete question is:
Given the equation representing a system at equilibrium:
- N₂(g) + 3H₂(g) ⇌ 2NH₃(g) + energy
what changes occur when the temperature of this system is decreased?
<h2>Solution</h2>
Modifying the temperature of a system in equilibrium changes the equilibrium constant and the equilibrium position (concentrations) of the system.
When the temperature is decreased, following LeChatelier's principle that the system will react in a way that seeks to counteract the disturbance, the reaction will shift toward the reaction that produces more heat energy to compensate the temperature decrease.
Thus, decreasing the temperature of the system will favor the forward reaction, more N₂(g) and H₂(g) will be consumed and more NH₃(g) and energy will be produced. Hence, the equilibrium will shift rightward.
A. Bacteria are stored in the lymph nodes
Answer:
Option A. Double Replacement
Explanation:
A double displacement reaction is a kind of reaction in which there is an exchange of the ions of the two reactants to form a different products. In the equation, K in KOH displaces H in H3PO4 to form K3PO4 and also, the H combines with OH to form water.
H3PO4+3KOH -> K3PO4+3H20
