Explain the term rate law
Did you know?
WebOne way is to use the method of initial rates. A rate law shows how a change in concentration affects the rate. The equation for a component A is #"rate" = k["A"]^m#, where #m# is the order of the reaction. Zero Order #"rate" = k["A"]^0 = k# The rate does not depend on the concentration. Whatever you do to the concentration, the rate will not ... WebThe rates of chemical reaction are, in general, highly sensitive to temperature. Reaction rates increase as the temperature increases. The temperature dependence of the …
WebSuppose that a company's sales were $\$ 5,000,000$ three years ago. Since that time sales have grown at annual rates of $10$ percent, $-10$ percent, and $25$ percent.

This is the rate law: \[\text{rate} = k[A]^x[B]^y \nonumber \] Next, the rate law equation from experiment 2 must be divided by the rate law equation for experiment 1. Notice that the [B] y term cancels out, leaving "x" as the unknown variable. Simple algebra reveals that x = 0.
WebJan 2, 2024 · For a general chemical reaction: aA + bB → cC + dD. the rate of the chemical reaction may be calculated as: Rate = k [A] a [B] b. Rearranging the terms, the rate constant is: rate constant (k) = Rate / ( [A]a[B]a) Here, k is the rate constant and [A] and [B] are the molar concentrations of the reactants A and B.
