The rate of enzyme reaction is refered to as the velocity of the reaction. It is most common to express the velocity in amount of product formed per minute. The initial reaction velocity, v0, of an That's the final time minus the initial time, so that's 2 - 0. So the rate of reaction, the average rate of reaction, would be equal to 0.02 divided by 2, which is 0.01 molar per second. So that's our average rate of reaction from time is equal to 0 to time is equal to 2 seconds. First of all, it is not known what the question is: The shortcut "enzyme velocity" may mean the "enzymatic reaction rate". Only that this rate depends on the initial substrate concentration (five

Thus, the rate of a reaction can be calculated by multiplying the rate constant by the substrate concentration (amount) or by determining reaction velocity (V). For each substrate concentration, calculate the rate (velocity) of reaction ( Absorbance units produced per unit Time). This will enable you to plot a graph of   Resources to help support the enzyme reaction rate practical element of A-Level, Most importantly the Maximal Velocity (Vmax), which is when the enzyme is  Velocity is inversely proportional to enzyme concentration. The maximum rate of reaction is reached as the substrate concentration increases indefinitely. The velocity of a reaction is defined as the increase in product /time An important point to note here is the units of the rate constant for a first order reaction are  where k is the rate constant of the reaction (velocity coefficient) and the expressions in the square brackets are the concentrations of the reactants.

The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.

The rate law or rate equation for a chemical reaction is an equation that links the reaction rate with the concentrations or pressures of the reactants and constant parameters (normally rate coefficients and partial reaction orders). For many reactions the rate is given by a power law such as = [] [] where [A] and [B] express the concentration of the species A and B (usually in moles per liter The speed or rate of a chemical reaction is the change in concentration of a reactant or product per unit time.   To be specific, it can be expressed in terms of: the rate of decrease in concentration of any of the reactants the rate of increase in the concentration of any of the products The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant. The initial rate of a reaction is the instantaneous rate at the start of the reaction (i.e., when t = 0). The initial rate is equal to the negative of the slope of the curve of reactant concentration versus time at t = 0. The velocity of chemical reaction at a given moment of time is proportional to the concentrations of reagents raised to certain power: v = k[A] n [B] m, for reaction aA + bB =
