Use the data in the table below to determine the rate law given the equation: 2A +3B+ C D Trial Rate of Production of D 2.0 x 10-3 40 x 10-3 40× 10-3 8.0 x 10-3 (mol L-1) (mol L-1) Mmol L-1) -1 0.01 0.02 0.01 0.01 0.01 0.01 0.02 0.01 0.01 0.01 0.01 0.02 2 4 Show work for finding the order of A: Equation: Substitution Rate of decrease: Show work for finding the order of B: Equation Substitution: Rate of decrease: Show work for finding the order of C: Equation: Substitution Rate of decrease: Write the complete Rate law using k for the rate constant

Explanation / Answer

order w.r.t A

(a1/a2)^x = (r1/r2)

(0.01/0.02)^x = (0.002/0.004)

x = 1

order w.r.t B

(a1/a3)^x = (r1/r3)

(0.01/0.02)^y = (0.002/0.004)

y = 1

order w.r.t C

(a1/a4)^z = (r1/r4)

(0.01/0.02)^z = (0.002/0.008)

z = 2

rate law , rate = k[A][B][C]^2
