Reaction Velocity Calculator:
Enter the values of concentration of product, CP(M) and time, T(s) to determine the value of reaction velocity, RV(M/s).
Reaction Velocity Formula:
Reaction velocity, often referred to as the rate of reaction, is a measure of how quickly a chemical reaction occurs. It is fundamental in the fields of chemistry and chemical engineering, as it determines how fast reactants are converted into products.
Reaction velocity is influenced by various factors, including temperature, pressure, concentration of reactants, and the presence of catalysts.
The velocity of a reaction can be described by the change in concentration of a reactant or product per unit time. In a practical sense, increasing the reaction velocity can lead to more efficient production processes in industrial settings.
Conversely, controlling or slowing down reaction velocities is crucial in cases where rapid reactions might be hazardous.
Reaction velocity, RV(M/s) in molarity per seconds is calculated by dividing the concentration of product, CP(M) in moles per litre by time, T(s) in seconds.
Reaction velocity, RV(M/s) = CP(M) / T(s)
RV(M/s) = reaction velocity in Molarity per seconds, M/s.
CP(M) = concentration of the product in moles per litre, M.
T(s) = time in seconds, s.
Reaction Velocity Calculation:
1.Calculate the reaction velocity of a reaction that produces 0.5 moles of product in a 2-liter solution over 10 seconds.
Given: CP(M) = 0.5 / 2 = 0.25M, T(s) = 10s.
Reaction velocity, RV(M/s) = CP(M) / T(s)
RV(M/s) = 0.25 / 10
RV(M/s) = 0.025m/s.
2.Determine the time if 1.2 moles of product are formed in a 1.5-liter solution with reaction velocity of 0.00444m/s.
Given: CP(M) = 1.2/ 1.5 = 0.8M, RV(M/s) = 0.00444m/s.
Reaction velocity, RV(M/s) = CP(M) / T(s)
T(s) = CP(M) / RV(M/s)
T(s) = 0.8 / 0.00444
T(s) = 180s.
