Sometimes a reaction depends on catalysts to proceed. In that case, changing the concentration of the catalyst can speed up or slow down the reaction. For example, enzymes speed up biological reactions, and their concentration affects the rate of reaction. On the other hand, if the enzyme is ...
The effect of temperature on rate of reaction is just one of the things that can affect how a reaction proceeds, that is, how quickly whatever reactants are present become transformed into products. Of course, many of these factors are active at all times and can have competing influences o...
The rate of reaction is simply how fast the reaction occurs. Some reactions, like explosions, are very fast. Other reactions, like the rusting of iron, are much slower. Several things can affect the rate of the reaction including the temperature, pressure, or presence of a cataly...
10 How does the addition of a catalyst to a reaction affect the shape of the Maxwell-Boltzmann distribution curve? B A There is no change. B The peak moves to the left and is higher. C The peak moves to the right and is lower. D The total are a under the curve increases. ...
Explain the rate of reaction and the factors that affect the rate of reaction. a) Explain how temperature affects the rate of a reaction. b) Explain how concentration affects the reaction rate. c) Explain how a catalyst affects the reaction rate. One of the factors th...

Also, the DMFC requires a relatively large amount of platinum to act as a catalyst, which makes these fuel cells expensive. Reversible Fuel Cells A reversible fuel cell combines two methods of energy production, uniting one of the previous fuel cell types with a solar or a wind generator. ...
can increase the rate of the reaction and promote higher yield, while in other cases, lower temperatures may be more effective. Careful consideration of the reaction kinetics and the properties of the reactants and products can help determine the optimal temperature for a given reaction. ...
How do structure and topology of the catalyst affect water promotion or inhibition effects?In this activity article, team members of Yanhui Yang (professor at the School of Chemistry and Molecular Engineering at the Nanjing Tech University) and Daniel E. Resasco (professor at the School of ...
These identify a few distinct chemical species whose relative energies we could adjust to achieve a faster or slower net reaction rate. Their relative energies could be adjusted by a variety of practical approaches, such as adding or modifying a catalyst, modifying the solvent, or simply modifying...
