4 days ago · As concentration of a substance is usually expressed as number of mole of a substance in unit volume of mixture, unit of rate of reaction turns out to be \(mol/cm^3.s\) . \[A+2B \to 3C+2D\]Initially, concentration of reactants A and B is 6 \(mol/cm^3\).What will be average rate of reaction when concentration of A drops to 4 \(mol/cm^3\) in 2 ...
4 days ago · In chemistry, the rate equation (also known as the rate law or empirical differential rate equation) is an empirical differential mathematical expression for the reaction rate of a given reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) only.

Hence, the rate of the reaction is determined by the concentration of the reactants. Formula Used: The first order rate equation, $ {\text {A = }} { {\text {A}}_ {\text {0}}} {\text { }} { {\text ...
3 days ago · May 2024 9:14:01. Determine the Concentration of the Unknown Strong Acid. In this activity you will use the virtual lab to determine the concentration of a strong monoprotic acid. To do this, you can perform a titration using NaOH and phenolphthalein found in the virtual lab.
5 days ago · Normality is also a way to define concentration. It is defined as the number of gram equivalents present per $1000mL$ of solution. Equivalent mass is calculated by dividing the molecular mass of substance with valency. Note: Molarity and molality both are two different terms.
