In which situation can Le Chatelier’s principle be applied?(1 point)
It can be applied when a reaction happens in a single direction, and environmental conditions are kept constant.
It can be applied when a reaction happens in a single direction, and environmental conditions are changed.
It can be applied when a reaction is reversible, and environmental conditions are kept constant.
It can be applied when a reaction is reversible, and environmental conditions are changed.
i have a good grade in chem so i wasnt worried about it if it was wrong or not, BUT asbcdg IS WRONG. you cant just give your answers without the written part next to it because they do switch around. So the correct ones are:
1- B: The forward reaction would increase to start reducing the concentration of N2-
2- C: It can be applied when a reaction is reversible, and environmental conditions are changed
3-B: The equilibrium will shift to the left
4-C: Adding steam allows more molecules of the reactants to collide, causing the rate of the forward reaction to increase
5-B: An increase in the concentration of CO
sorry if any of those are wrong, but these are the correct answers as of 2-25-22
lemonfairy is 100% correct! THANKS
thank you lemofairy!
Did you have the answers for this quick check?
It can be applied when you try to convince your friend to go see a horror movie with you, and you use the principle of Le Chatelier to change the environmental conditions of their courage and bravery. But in the world of chemistry, Le Chatelier’s principle can be applied when a reaction is reversible, and environmental conditions are changed.
The correct answer is:
Le Chatelier's principle can be applied when a reaction is reversible, and environmental conditions are changed.
Explanation:
Le Chatelier's principle states that a system in equilibrium, or in a state of balance, will adjust to counteract any changes imposed upon it. This principle can be applied to reactions that are both reversible and have environmental conditions changed.
When the environmental conditions, such as temperature, pressure, or concentration, are altered, the system shifts in a way that reduces the effect of the change. For example, if the temperature increases, the system will try to decrease the temperature by favoring the endothermic reaction (which absorbs heat) or by absorbing heat from the surroundings. Conversely, if the temperature decreases, the system will try to increase the temperature by favoring the exothermic reaction (which releases heat) or by releasing heat to the surroundings.
Similarly, if there is a change in pressure or concentration, the system will adjust to counteract the change. If the pressure increases, the system will try to decrease the pressure by favoring the side with fewer moles of gas (if applicable). If the concentration of reactants or products is changed, the system will shift in a way to restore the balance by either increasing or decreasing the concentration of the affected species.
It is important to note that Le Chatelier's principle is not applicable when the reaction only occurs in a single direction. In such cases, the system cannot shift to counteract any changes, as there is no reverse reaction to restore the balance. Similarly, if the environmental conditions are kept constant, there are no changes to counteract, so the principle does not come into play in such instances.
