Express your answer with the appropriate units. Indicate the
multiplication of units, as necessary, explicitly either with a
multiplication dot or a dash.
The integrated rate laws for zero-, first-, and second-order may be arranged such that they resemble the...

Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash. k0th = 2.07×10−4 Ms (I did this one already) Part B: What was the initial reactant concentration for the reaction described in Part A? Express your answer...
For a first-order reaction, the half-life is constant. It depends only on the rate constant k and not on the reactant concentration. It is expressed as t1/2=0.693kt1/2=0.693k For a second-order reaction, the half-life depends on the rate constant and the concentration of the reactant and so is expressed as t1/2=1k[A]0 Part A. A certain first-order reaction (A→products) has a rate constant of 3.00×10−3 s−1 at 45 ∘C∘C. How many minutes does it take for the concentration of the reactant, [A],...
QUESTION 7 Give the characteristic of a second order reaction having only one reactant. O The rate of the reaction is proportional to the natural logarithm of the concentration of the reactant. O The rate of the reaction is not proportional to the concentration of the reactant. 。The rate of the reaction is proportional to the square of the concentration of the reactant. The rate of the reaction is proportional to the square root of the concentration of the reactant....
