Question

can someone help with this question?

Answer 1

Is M the molarity?

Answer 2

yeah

Answer 3

since the half-life is dependent on the concentration it's a second order reaction

Answer 4

oh wait it can be a zeroth reaction as well

Answer 5

2ed is right

Answer 6

okay, use the half life formula: t1/2 = 1 / k [Ao]

Answer 7

for the 2nd part

Answer 8

can u help with another question

Answer 9

@aaronq

Answer 10

sure post it

Answer 11

instead of [C], it should be [D]. C is a product, not a reactant

Answer 12

so (a)(d)

Answer 13

it says its wrong

Answer 14

@aaronq

Answer 15

hm maybe try using the slow step only?

so rate=k[B][D]

Answer 16

it says this You are on the right track, but your answer includes an intermediate that is not present in the overall reaction. Use the equilibrium step to find a substitute expression for that intermediate in the rate law.

Answer 17

so idk

Answer 18

did it say that when you put [A]^2[D] or [B][D]?

Answer 19

the formation of [B] is dependent on[A]^2

so d[B]/dt=-d[A]^2/dt

Answer 20

[B][D]
