Question

For the reaction 5A + 6G 2D + 3E, the following initial rates of reaction were found.




Determine the rate law, filling in the appropriate spaces below.

R = k [A] [G]





Determine the overall order of the reaction.





Determine the rate constant (with appropriate units) for this reaction. Report your answer to three significant figures. When entering units, use "^" to indicate superscripts and a "*" to separate various units (i.e. M^-6*s^-1)





Determine the rate of reaction (in M/s) when [A] = 0.326 M and [G] = 0.651 M. Report your answer to three significant figures.

[A]o/M [G]o/M Initial Rate of Reaction / (M/s) 0.834 0.395 1.90×10-1 0.278 0.395 1.90×10-1 0.834 0.132 2.11×10-2

Explanation / Answer

reaction is zero order with respect to A

second order with respect to G

rate law as follows

rate = K [G]2

overall order = 2

K = rate / [G]2

K = 1.9 x 10-1 / [0.395]2

K = 1.9 x 10-1  / 0.156

K = 1.22 M-1 s-1

rate = 1.22 [0.651]2

rate = 5.17 x 10-1 M/s
