    This is question #6 from Chemistry Test 3 QVAULTDAT:


    Determine the numerical value of the rate constant for the reaction A+B-->C from the experimental data given below.


    E [A] Rate
    1 .45 .26 1.00
    2 .90 .26 1.05
    3 .90 .52 2.03

    A) k=(0.26)(0.45)

    B) k=0.26

    C) k=(0.26)^2(0.45)

    D) k=(0.26)(0.25)^2

    E) k=(0.31)^3(0.25)

    How is the correct answer B??? I keep getting K = 1/.26 = 4 since R=K. Does anyone know why B is the correct answer?

    yeah I think you are right.
    rate=k where =0.26 rate=1
    then k=1/0.26
    or rate=k(0.26)

    I also agree with this analysis.
