How to Change Font Color in Adobe Reader. March 31, 2015. Adobe created the portable document format, or PDF, so that files could be shared easily across computer platforms. Adobe PDF documents can be multi-page documents or single-page documents, and can include an array of graphics and text in an assortment of colors.
Which fact is most important in explaining how enzymes speed reactions? Very low potential energy tends to make molecules unstable. High-energy collisions are less common than low-energy collisions. It takes less energy to break a hydrogen bond than a covalent bond. Large molecules collide more energetically than small molecules. Every reaction step adds to the time required for the overall reaction. Study Enzyme Activity.
Rate-limiting reaction is the slowest reaction in a series of reactions. It is used to calculate the rate law of the overall reaction. Recall from thermochemistry that slow reactions tend to have higher activation energy (energy âhillâ). Slower reactions have to climb a higher energy hill to produce transition states and, subsequently, products; therefore, rate-limiting reaction will have the highest activation energy of all reactions in the series.
