For a reaction, A → products, with the rate law:  Rate = k[A]2,     (a) a plot of ln[A] vs. time gives a straight line.     (b) a plot of Rate vs. concentration gives a straight line.     (c) both (a) and (b) are correct.     (d) a plot of 1/[A] vs. time gives a straight line.     (e) both (b) and (d) are correct.

Considering the rate law, rate = k[A]°[B]?, which of the following statements is correct? A) The reaction is the third order in A and third order overall. B) The reaction is the second order in B and second order overall. C) The reaction is the third order in A and fifth order overall. D) The reaction is the second order in B and third order overall.

help w this question plz

State whether the followingis true or false. If true , explain your reason. if false, explain your reason and provide a correct statement. a) The rate of consumption of reactants and the rate of formation of products is always equal to the rate of reaction  (True or false) b) In a reaction A + B ---> P, if the reaction is present in a much higher concentration than reactant A, you can determine the order of reaction with respect to B (True or false) c) In any chemicalreaction A + B ---> C, the concentration of A and B affect the rate of formation of C (True or false)

25.)  A reaction has a rate constant of k = 0.0870 M-1·s-1. How many seconds will it take for the initial amount of a reactant to decrease from 0.768 M to 0.272 M?   Your Answer:

See attached image for question A.) What is the order of the reaction in A? B.) What is the rate of reaction when the initial concentrations are [A]= 0 M and [B]= 4.4x 10-2M?

H2 reacts with ClF. Someone thinks this is the mechanism:                               H2(g)  +  ClF(g) → HCl(g)  + HF(g)                               HCl(g)  +  ClF(g) →  Cl2(g)   + HF(g) (a)     Write the balanced equation for the overall reaction. (b)  Identify any intermediates in the mechanism, if any. (c) identify and catalysts in the mechanism, if any. (d) Write rate laws for each elementary reaction in the mechanism. (e)  If the first step is slow and the second one is fast, what rate law do you expect to be observed for the overall reaction?

Which of the following statements about rate laws is FALSE? A) Rate laws can only be determined experimentally. B) Rate laws tell us information about the mechanism of the chemical reaction under study. C) The rate law for the chemical reaction A + B + 20 –D must be rate = k[A][B][C]² %3D D)A rate law can only be written for the elementary reactions of a given chemical reaction.

For a reaction that follows the general rate law, Rate = k[A]0[B]3, what will happen to the rate of reaction if theconcentration of A is tripled and the concentration of B is doubled?(a) Increase by a factor of 6(b) Increase by a factor of 8(c) Increase by a factor of 9(d) Increase by a factor of 12

The scenes depict four initial reaction mixtures for thereaction of A (blue) and B (yellow), with and without a solidpresent (gray cubes). The initial rate, -Δ[A]/Δt(in mol/L s),is shown for each sphere representing 0.010 mol and the con-tainer volume at 0.50 L.(a) What is the rate law in the absence of a catalyst?(b) What is the overall reaction order?(c) Find the rate constant.(d) Do the gray cubes have a catalytic effect? Explain.
