The rate of a chemical reaction is, perhaps, its most important property because it dictates whether a reaction can occur during a lifetime. Knowing the rate law, an expression relating the rate to the concentrations of reactants, can help a chemist adjust the reaction conditions to get a more suitable rate.

['Reaction rate is calculated using the formula rate = Δ[C]/Δt, where Δ[C] is the change in product concentration during time period Δt.', 'The rate of reaction can be observed by watching the disappearance of a reactant or the appearance of a product over time.']

Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate.

Factors That Affect the Rate of Dissolving A: The rate of dissolving is influenced by several factors, including stirring, temperature of solvent, and size of solute particles.

The reaction rate is the change in the concentration of either the reactant or the product over a period of time. The concentration of A decreases with time, while the concentration of B increases with time.

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place. We define reaction rate as the speed at which reactants are converted into products. ... Chemical kinetics is the part of physical chemistry that studies reaction rates.

By increasing the enzyme concentration, the maximum reaction rate greatly increases. Conclusions: The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.

Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

What are the factors that influence basal metabolic rate (BMR)? Age, nutrition, and activity are factors that influence basal metabolic rate. Factors that influence basal metabolic rate are: Body size: Metabolic rate increases as weight, height, and surface area increase.

Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions. It is only these collisions (possessing at least the activation energy for the reaction) which result in a reaction.
