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...
Give an example that which catalyst is useful. The Collision Theory: The collision theory is the theory that best explains how various factors affect the rate of a chemical reaction. Generally, the factors affect the physics of the reacting particles which have to collide...
Like the SOFC, these fuel cells are also best suited for large, stationary power generators. They operate at over 600 degrees Celsius, so they can generate steam that can be used to generate more power. The cell uses a molten salt solution as a catalyst that separates hydrogen particles from...
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 catal...
How does an increase in reactant concentration affect the rate of reaction? How do you find order of reaction from chemical equation? Discuss the various factors that may alter the rate of a chemical reaction. What is formed in a chemical reaction?

In a hydrogen fuel cell, a catalyst breaks hydrogen molecules in the anode into protons and electrons. The protons move through the exchange membrane, toward the oxygen on the cathode side, and the electrons make their way through a wire between the anode and cathode. On the cathode side, ...
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...
The need to limit antibiotic therapy due to the spreading resistance of pathogenic microorganisms to these medicinal substances stimulates research on new therapeutic agents, including the treatment and prevention of animal diseases. This is one of the g
