WebTheoretically, weakly acidic drugs (eg, aspirin) are more readily absorbed from an acid medium (stomach) than are weakly basic drugs (eg, quinidine ). However, whether a drug is acidic or basic, most absorption occurs in the small intestine because the surface area is larger and membranes are more permeable (see Oral Administration ). WebChemical reaction rates can be expressed in terms of the rate of production of any reaction product or as the rate of decrease in the concentration of any reactant. The individual steps in a chemical reaction sequence are termed elementary reactions. A number of consecutive elementary reactions may be responsible for a given chemical change. WebSep 2, 2024 · Solution : (a) Surface area of the reactant is increased When surface area of the reactant is increased, there is greater contact between the reactant molecules. Hence rate of reaction increases. (b) Temperature of the reaction is decreased Kinetic energy of the molecules depends upon the temperature. css link to html

WebOct 29, 2024 · The rate of many chemicals reactions doubles for each 10 °C increase in temperature. The “rule” applies to most, but not all reactions. For example, many biochemical reaction rates double with much smaller temperature increases. Also, there is an upper temperature limit above which a reaction will slow or stop. Pressure WebIncreasing the surface area of a solid reactant increases the reaction rate. By increasing surface area, there are more collisions per unit of time. That's why many solids are powdered using a mortar and pestle before being used in a reaction. Examples of other reactions where surface area is important are:

WebReaction rate increases with concentration, as described by the rate law and explained by collision theory. As reactant concentration increases, the frequency of collision increases. The rate of gaseous reactions increases with pressure, which is, in fact, equivalent to an increase in the concentration of the gas.

WebOnce all of the substrate is bound, the reaction will no longer speed up, since there will be nothing for additional enzymes to bind to.
