Why is catalyst effective in small amounts?
Catalysts are effective in small amounts because they facilitate chemical reactions by lowering the activation energy required for the reaction to occur, allowing reactants to convert to products more easily. They are not consumed in the reaction, meaning a single catalyst molecule can participate in multiple reaction cycles. This efficiency allows a small quantity of catalyst to influence a large number of reactant molecules, enhancing the overall reaction rate without the need for large amounts of the catalyst itself.
Why use reactant in the powdered form?
A lump of solid has a much lower surface area compared to a powdered catalyst. Since most chemical reactions that are catalysed by solid phase catalysts (heterogeneous catalysts) occur on the catalyst surface more surface area = faster reaction.
What things might be considered when deciding between iron and ruthenium as a catalyst?
Factors to consider when deciding between iron and ruthenium as a catalyst include cost, reactivity/selectivity of the catalyst towards the desired reaction, availability, and potential environmental impact. Iron is more abundant and cost-effective but may have lower reactivity compared to ruthenium, which is more efficient but expensive and less earth-abundant. Additionally, the specific reaction conditions and requirements may also influence the choice of catalyst.
What is a broken pot catalyst?
A Catalyst used to "Break Down" Long Hydrocarbons into smaller, more useful ones...
Which surface has the biggest lumps on its surface ice rubber or steel?
Steel has the biggest lumps on its surface compared to ice and rubber. This is because steel is a solid material with a rough and uneven surface, while ice and rubber are usually smoother and more uniform in texture.
Why is a catalyst more effective in powdered form?
Higher surface area is available for the chemical reaction.
Why you use the porcelain chips as the catalyst for the dehydration of ethanol?
Porcelain chips are used as a catalyst for the dehydration of ethanol because the rough surface of the chips provides a large surface area for the reaction to occur, allowing for more contact between the reactants and catalyst. This helps to enhance the rate of the dehydration reaction and improve the overall efficiency of the process.
Why are rough surfaces good emitter of heat?
Rough surfaces have a larger surface area, which enables them to emit more thermal radiation compared to smooth surfaces. This increased surface area allows for more heat transfer between the object and its surroundings, making rough surfaces more effective emitters of heat.
Is the force is greater on a smooth surface or on a rough surface?
The force is greater on a rough surface compared to a smooth surface, due to the increased friction between the surfaces. The rough surface provides more resistance to motion, requiring more force to overcome the friction.
Does a rough bumpy surface produce more or less friction?
A rough, bumpy surface typically produces more friction compared to a smooth surface. The irregularities on the rough surface create more contact points between surfaces, leading to increased resistance and friction during movement.
What type of surface rough or smooth would absorb and radiate heat more rapidly?
A rough surface would absorb and radiate heat more rapidly compared to a smooth surface. This is because a rough surface has more surface area in contact with the surrounding environment, allowing for more efficient transfer of heat through conduction and radiation.
Why is a catalyst spread over a large surface area?
So it is more efficient.
Is it true that more force must be applied when pushing something across rough surface?
Yes, it is true that more force is required to push something across a rough surface compared to a smooth surface. This is because the rough surface creates more friction, which resists the motion of the object being pushed.
Does a basketball roll faster on a smooth surface or a rough surface?
A basketball will roll faster on a smooth surface due to less friction compared to a rough surface. The rough surface creates more resistance, slowing down the ball's movement.
Is greater force needed to move an object over a smooth surface than over a rough surface?
No, greater force is typically needed to move an object over a rough surface compared to a smooth surface. This is because the irregularities on a rough surface create more friction, making it harder to overcome resistance and move the object. Smooth surfaces offer less resistance to movement.
Does a rough bumpy surface get more friction or less friction?
more
Is there more friction on a rough surface show a picture?
Yes, there is more friction on a rough surface compared to a smooth surface. Rough surfaces have more irregularities that create greater interlocking between the surfaces in contact, leading to higher friction forces. Unfortunately, I'm unable to show pictures.
