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 cation is a positive charged ion and a anion is a negatively charged ion. An electron will make a cation if it is lost and a anion if it is gained.
The etymology of the prefix cat- means the way down: so think of the sun setting down and losing light. Cat = losing electrons (Such as in a CAThode ray).
The etymology of the prefix -an means upwards. So think of the sun rising up and becoming brighter. An = gaining electrons and becoming overall more negative as electrons are negatively charged.
Answer:
the scientific study of the relations between heat and other forms of energy
I need context but here’s the definition from my notes: a substance that can react with acids and neutralize them
solution:
You need to find the frequency, and they have already given you the wavelength. And since you already know the speed of light, you can use formula (2) to answer this problem. Remember to convert the nano meters to meters because the speed of light is in meters.
