What factor in reaction rate is related to the amount of reactants?

This is the concentration of reactants.


Why does yield of reaction decrease with increase in amount of catalyst?

It doesn't. The whole point in a catalyst is that the only thing it does, is speeds up the reaction. It does not change or affect it in any other way. However, factors which can change yield of reaction are temperature and pressure. For example, take the manufacture of ammonia. Pressure is measured in Atmospheres (atm) Temperature is measured in degrees celcius (oC) Companies that manufacture ammonia generally use 10 atms, and at least 450oC Increasing the pressure above around 10 atms, reduces yield. Having temperature that high, also reduces yield, but as well as the catalyst, it increases the speed of the reaction.


What happens to pressure if you increase the ATM?

If you increase the atmospheric pressure, the pressure will also increase. This is because atmospheric pressure is the pressure exerted by the weight of air above a certain point, so increasing the amount of air causes an increase in pressure.


Engineers must design a process for producing a large amount of ammonia at reasonable cost. Which criterion must the process meet?

Answer: A. The process needs to produce significant amounts of ammonia= D. The process needs to be able to be performed safely.​ APEX Which two criteria are the most important for engineers to consider when developing a process to produce ammonia? A. The process needs to produce significant amounts of ammonia. B. The process needs to copy something that has already been done. C. The reactants need to come from natural sources. D. The process needs to be able to be performed safely.​


Why don't the amount of reactants and products change in a reversible reaction?

The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.

What happens to the mass of reactants in a chemical reaction?

The reactants will form products, so the amount of reactants will decrease, proportionally to the increase in products. The amount can be expressed in mass, concentration or moles.


What happens when you increase the amount of co2 given to plants?

The rate of photosynthesis increases. Carbon dioxide is a reactant in photosynthesis; if the reactants are increased, the reaction goes faster.


Why is high pressure necessary for making ammonia?

When producing ammonia, there is not a 100% change from reactants into products. In fact, around half of the reactants will change into ammonia, and then equilibria is reached and the amount of ammonia will stay the same. Increasing the pressure shifts the equilibria, so that more ammonia is produced when an equilibria is reached, making the process more efficient. Hypothetical example: 1 litre of reactants (normal pressure) -----> 0.5 litre reactants and 0.5 litre ammonia 1 litre of reactants (high pressure) -------> 0.2 litre reactants and 0.8 litre ammonia


What would happen to the amount of products if you increase the amount of one of the reactants?

Increasing the amount of one reactant typically increases the amount of products produced until the reactant is used up. Once the reactant is exhausted, the reaction will reach equilibrium and the amount of products will no longer increase.


What happens when you add grape juice to ammonia?

Depending upon the amount of ammonia that you drink, it will either make you sick or kill you.


Which of the following would decrease the amount of time of a glow stick to stay bright?

increase the temparature of the reactants


How can the yield of ammonia be increased?

To increase the yield of ammonia in the Haber process, you can: Increase the pressure: Higher pressure shifts the equilibrium towards the product side, increasing the amount of ammonia produced. Optimize the temperature: Lower temperatures are favorable for ammonia production, but it’s a balance to prevent the reaction from being too slow. Use a suitable catalyst: Iron catalysts are commonly used to speed up the reaction without being consumed. Optimize the ratio of reactants: Ensuring the ideal ratio of nitrogen and hydrogen in the reaction mixture can also improve the yield of ammonia.


What leads to the increase in the rate of a chemical reaction?

Many things lead to an increase in the rate of chemical reactions. These factors include: - Addition of Catalysts - Light (only in some reactions) - Increase in temperature - Increase in Pressure - Increase in amount of reactants


What is is an yield?

The amount of product which should be produced from a given amount of reactants where one of the reactants is a limiting reagent.


What factor in reaction rate is related to the amount of reactants?

This is the concentration of reactants.


What happens to the density of a given substance if you increase the amount of the substance that you have?

Nothing happens if the volume is also allowed to increase.


What happens to temperature with little ozone?

Ozone is a greenhouse gas. Increase in amount of ozone will increase the temperature of the atmosphere.
