The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. Reaction rates can vary dramatically. For example, the oxidative rusting of iron under Earth's atmosphere is a slow reaction that can take many y… WebRates and temperature.

WebSubstituting in the reaction-rate expression, r = k (T )c A, and using the number of moles of A, n A = c A V R yields dn A dt = k (T )n A (6.20) Notice the temperature dependence of k (T ) prevents us from solving this di erential equation immediately. We must solve it simultaneously with the energy balance, which provides the information WebThe rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, Vmax. The relationship between rate of reaction and concentration of substrate depends on the affinity of the enzyme for its substrate. This is usually expressed as the Km(Michaelis constant) of the enzyme, an inverse measure dewalt 8-1/4-in compact table sawWebIf the rate of people entering the water is equal to the rate of people getting out of the water, then the system is at equilibrium!
