Quick Answer. Most wool comes from sheep, although some wool is harvested from goats, muskoxen, rabbits and certain camelid species. Wool produces a unique textile with qualities that cannot be found in fur, such as its crimped texture, elasticity and tendency to grow in clusters for easy harvesting. Continue Reading.
1 This is due to an increase in the number of particles that have the minimum energy required. The reaction rate decreases with a decrease in temperature.  Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction.
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.
