Question

Determine the rate law, including the values of the orders and rate law constant, for the following reaction using the experimental data provided.
A + B products
Trial [A] [B] Rate
1 0.30 M 0.25 M 1.2 × 10-2 M/min
2 0.30 M 0.50 M 4.8 × 10-2 M/min
3 0.60 M 0.50 M 9.6 × 10-2 M/min

Answer 1

@aaronq ?

Answer 2

K=7.111
\[R=KA ^{3}B ^{2}\]

Answer 3

are you saying that R=K A^3 B^2 is the rate ?

Answer 4

The reaction is third order A and second order B

Answer 5

i know that trial 3 is twice as trial 1

Answer 6

thats not right.

Note trial 1 and trial 2, gives you \([B]^2\)

and trial 2 and trial 3 gives \([A]^1\)

Answer 7

@aaronq so what do you say the rate is ?

Answer 8

at what point?

Answer 9

well the question says Determine the rate law, including the values of the orders and rate law constant, for the following reaction using the experimental data provided.
so idk what point is that ?

Answer 10

so we figured out the rate law, you just need the value for k - the rate constant.

Answer 11

K=7.111

Answer 12

what is next ?

Answer 13

thats all they asked for

Answer 14

ohh so how do i explain this ?

Answer 15

oh nvm you already told me that ! thanks for helping !!

Answer 16

@amematsro thanks too!

Answer 17

no problem!

Answer 18

no problem
