Question

Given the data calculated in Parts A, B, C, and D, determine the initial rate for a reaction that starts with 0.55 M of reagent A and 0.90 M of reagents B and C?

Express your answer to two significant figures and include the appropriate units. Indicate the multiplication of units explicitly either with a multiplication dot or a dash.

Order of A: 2

Order of B: 0

Order of C: 1

k = 7.5×10?3 M?2?s?1

For the reaction A +B C D E, the initial reaction rate was measured for various initial concentrations of reactants. The following data were collected: Al CB1 IC1 Initial rate Trial (M) (M) 1 0.20 020 0.20 6.0x10-5 1.8x10-4 0.20 0.20 0.60 2.4x10-4 0.40 0.20 0.20 2.4x10-4 0.40 0.40 0.20

Explanation / Answer

rate = k [A]^2 [C]

put values to get initial arte
rate = 7.5*10^-3 * (0.55)^2 * (0.90)
= 2.0*10^-3 M/s

Answer: 2.0*10^-3 M/s
