Considerations. Each chocolate-covered espresso bean contains 5 milligrams of caffeine, a stimulant that elevates your heart rate and blood pressure. Overconsumption of caffeine can lead to nausea, vomiting, tremors, restlessness and difficulty sleeping.
Summary. â¢ The pH value of a solution depends on the temperature. â¢ A pH value without a temperature value is meaningless. â¢ Solution temperature compensation converts measured pH to the pH at 25Â°C. â¢ Only pH values taken at the same temperature or converted using solution temperature compensation can be compared to each other.
If the solid is divided into smaller pieces, then there is greater surface area; therefore, more particles are able to react, and the reaction rate increases. Effect of temperature on reaction rate: An increase in the temperature of reactants usually results in an increase in the reaction rate.n this experiment, you will study various conditions and the effect they have on the collision of molecules. You will observe the effects of temperature, concentration, particle size (surface area), and catalysts on the rates of chemical reactions and then explain these effects in terms of the collision theory.
