Entropy can decrease in a reaction when a system transitions from a more disordered state to a more ordered state, often observed in processes like crystallization or the formation of complex molecules from simpler ones. This decrease typically occurs in a local context, as the overall entropy of the universe still tends to increase according to the second law of thermodynamics. Additionally, external energy input can drive reactions that lead to a decrease in entropy within a system. However, it’s important to remember that while entropy may decrease locally, the total entropy of the combined system and surroundings will increase.
What else can I help you with?
What would cause the greatest decrease in the rate of chemical reaction?
For most reactions, the lowering of the temperature of the reactants.
What reaction will cause the contain to feel colder?
Endothermic reactions can cause the container to feel colder. A simple example would be just mixing baking soda and vinegar.
What would cause a decrease in gas pressure in a closed container?
A decrease in gas pressure in a closed container could be caused by a decrease in temperature, which reduces the average kinetic energy of the gas molecules, leading to fewer collisions with the container walls. It could also be caused by a leak in the container allowing gas to escape, or by a chemical reaction that consumes gas molecules.
What temperature change do you think would be required to increase or decrease the reaction time by a factor of 2?
all chemical reaction has to be thought of to be there
The Haber process is typically carried out at a temperature of approximately 500rm circ C What would happen to the rate of the forward reaction if the temperature were lowered to 100rm circ C?
Lowering the temperature to 100°C would decrease the rate of the forward reaction in the Haber process. This is because lower temperatures slow down the kinetic energy of the particles, resulting in fewer collisions between molecules, which in turn reduces the rate of reaction.
What would cause entropy to decrease in a reaction?
The products becoming more ordered than the reactants
What would cause the greatest decrease in the rate of chemical reaction?
For most reactions, the lowering of the temperature of the reactants.
What reaction would cause decrease in entropy?
CO(g)+3H2(g)->CH4(g)+H2O(g)
What reaction will cause the contain to feel colder?
Endothermic reactions can cause the container to feel colder. A simple example would be just mixing baking soda and vinegar.
What change to a wire would cause its resistance to decrease?
Decreasing the length or increasing the thickness of the wire would cause its resistance to decrease.
What would happen to the entropy in the reaction 2O3 g 3O2 g?
It increases
What would most likely result in the greatest decrease in the rate of a chemical reaction?
Decreasing the temperature or changing the concentration of the reactants would most likely result in the greatest decrease in the rate of a chemical reaction. These changes affect the collision frequency and energy of the reacting molecules, slowing down the overall reaction rate.
What would cause breathing to decrease?
smoking can cause lots of trouble.
What happen to yield of sulfur trioxide if you increase the pressure and you decrease the pressure?
Increasing the pressure would increase the yield of sulfur trioxide because the reaction involves a decrease in volume. Decreasing the pressure would decrease the yield of sulfur trioxide because the reaction volume would increase.
What decrease would likely cause the selling price of houses to decrease?
Decreased mortgage interest rates and a decrease in construction workers' wages would both be likely to cause the selling price of a house to decrease.
How would a decrease in natality change the population?
A decrease in the birth rate will cause a decrease in population over time.
What would cause a decrease in gas pressure in a closed container?
A decrease in gas pressure in a closed container could be caused by a decrease in temperature, which reduces the average kinetic energy of the gas molecules, leading to fewer collisions with the container walls. It could also be caused by a leak in the container allowing gas to escape, or by a chemical reaction that consumes gas molecules.
