A reaction has a rate law of : rate = k [ClO3] [Cl] [H+]2. If the initial reaction rate is 3.2E3 M/s, then what is the rate constant if the initial concentrations are [ClO3]o= 0.10 M, [Cl]o= 0.10 M, [H+]o= 0.20 M ? (units are M3 " s1)
A) 1.6
B) 8.0
C) 1.2
D) 0.62
E) none of these

Best ResponseYou've already chosen the best response.0i think you would say 3.2 E3 M/s = k [0.10] [0.10] [0.2] k= (3.2E3/([0.10]*[0.1)]*[0.20])

Best ResponseYou've already chosen the best response.0actually wrong brackets... 1.6

Best ResponseYou've already chosen the best response.2\(\sf Rate = k[ClO_3^][Cl^][H^+]^2\)

Best ResponseYou've already chosen the best response.2So, K should be equal to ???

Best ResponseYou've already chosen the best response.01.6*0.10*0.20*0.10=3.2 E3 (the initial rate) so k is 1.6

Best ResponseYou've already chosen the best response.2Nuuuuu!!! \(\sf K=\Large \frac{Rate}{[ClO_3^][Cl^][H^+]^2}\)

Best ResponseYou've already chosen the best response.2You need to keep the order as given, I said you did a mistake. look above.. :(

Best ResponseYou've already chosen the best response.0i got 1.6 when i calclulated that

Best ResponseYou've already chosen the best response.2\(\sf K=\Large \frac{3.2 \times 10^{3}}{0.1\times 0.1 \times (0.2)^2}\)

Best ResponseYou've already chosen the best response.2Because the Rate Law is given as \(\sf Rate = k[ClO_3^][Cl^][H^+]^2\)
