Question

which of the following reactions would proceed at the fastest rate?

Answer 1

@Rushwr @Shikamaru11 @Shalante

Answer 2

A + B --> C Ea =100kJ
D+E --> F + G Ea 150kj
H --> I + J Ea = 250 kJ
Impossible to tell

Answer 3

these are endothermic reactions ain't that @Photon336

Answer 4

the question just gave like the activation energies

Answer 5

oh the activation then it's A as it has the lowest activation energy :) @Photon336

Answer 6

@Rushwr correct

Answer 7

next one

Answer 8

We have this reaction \[Cl_{2} +H_{2}O \rightarrow HCL + HCLO\]

Answer 9

so what we've to do with it :)

Answer 10

Cl_2 double arrow 2Cl* radical this step is fast
Cl* + H2O --> HCL + *OH slow
Cl* + *OH --> HCLO fast

1. which of the following are intermediates and why?

Cl* radical
*OH radical
Cl* and *OH
there is no intermediate

Answer 11

after this i'm going to close this and post another one

Answer 12

you mean 2-step reaction

Answer 13

so the question is @Shikamaru11 what are the intermediates in this reaction

Answer 14

well seems to be no intemediate here ??

Answer 15

an intermediate is something that's formed quickly and then disappears.

Answer 16

usually because it's unstable

Answer 17

sometimes it can be detected though

Answer 18

@rushwr @Shalante thoughts?

Answer 19

so Cl* and OH* are intermediates then

Answer 20

@Shikamaru11 I think OH is definitely an intermediate

Answer 21

Guys they both are intermediates looked up the answer

Answer 22

so my guess wasn't that bad @Photon336 :)

Answer 23

hahaw just GOD's perfect :) @Rushwr

Answer 24

yeah, it think it's because they disappear and arent present in the final products or as side products.

Answer 25

i'm going to close this and open another one
