In this reaction some reactant A is turned into some product B. The rate of reaction can be represented by a decrease in concentration of A over time or as the increase of B over time. This is written: rate=−Δ[A]Δt=Δ[B]Δt Since A decreases over time there is a negative s...
Reactant concentrations and pressures, temperature, and the presence of catalysts are some of those factors that can influence the rate of a reaction. However, the manner in which the rate of a reaction is expressed is consistent from one reaction to the next....
What are enzymes and how is the rate of enzyme reactions affected? And what are all the inhibitors and how they work? 1. What are enzymes? 2. What are their main properties? 3. Write an experiment to demonstrate the effect of temperature on enzyme reacti...
Determine the concentration of your product at each temperature. When the temperature rises above 40 degrees Celsius, you will see a decrease in the rate at which substrate is converted into product, because the enzyme is denatured. The point at which the product is being produced at the maximu...
Though scientists warn that global warming will likely continue for centuries because of the long natural processes involved, there are a few things we can do to decrease the effects. Basically, they all boil down to this: Don't use as much of the stuff that creates greenhouse gases. On a...
Or you can buffer a retinol serum by mixing moisturizer with it in the palm of your hand before applying it directly to your skin since the moisturizer acts as a buffering agent to decrease the potency of the retinol. Post-Retinol Skin Care...
Concentration of a substrate affects enzyme function in that increasing it causes the rate of reaction to increase, and decreasing it causes the rate of reaction to decrease. The rate of reaction would increase because there is more substrate to collide with the enzyme, which would then increase...
Bipolar plates are used to connect one fuel cell to another and are subjected to both oxidizing and reducing conditions and potentials. A big issue with bipolar plates is stability. Metallic bipolar plates can corrode, and the byproducts of corrosion (iron and chromium ions) can decrease the ...
We reveal the formation of nanocrystalline Al oxide and highlight the solute partitioning between the oxide and the matrix and segregation to the internal interface. The sharp decrease in partitioning content of Mg in the peak-aged alloy emphasizes the impact of heat treatment on the oxide ...
regulate or accelerate the rate of absorption. Every concept of enhancing the bio-availability and selectivity of pharmaceuticals will be related with the fact that lower doses are used. Another solution is the “smart drug” concept, which aims to produce pharmaceuticals that go into a given ...
