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

these are endothermic reactions ain't that @Photon336

the question just gave like the activation energies
Shikamaru11
  • Shikamaru11
oh the activation then it's A as it has the lowest activation energy :) @Photon336

@Rushwr correct

next one

We have this reaction \[Cl_{2} +H_{2}O \rightarrow HCL + HCLO\]
Shikamaru11
  • Shikamaru11
so what we've to do with it :)
Photon336
  • Photon336
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

after this i'm going to close this and post another one
Shikamaru11
  • Shikamaru11
you mean 2-step reaction
Photon336
  • Photon336
so the question is @Shikamaru11 what are the intermediates in this reaction
Shikamaru11
  • Shikamaru11
well seems to be no intemediate here ??
Photon336
  • Photon336
an intermediate is something that's formed quickly and then disappears.
Photon336
  • Photon336
usually because it's unstable
Photon336
  • Photon336
sometimes it can be detected though
Photon336
  • Photon336
@rushwr @Shalante thoughts?
Shikamaru11
  • Shikamaru11
so Cl* and OH* are intermediates then
Photon336
  • Photon336
@Shikamaru11 I think OH is definitely an intermediate
Photon336
  • Photon336
Guys they both are intermediates looked up the answer
Shikamaru11
  • Shikamaru11
so my guess wasn't that bad @Photon336 :)
Shikamaru11
  • Shikamaru11
hahaw just GOD's perfect :) @Rushwr
Photon336
  • Photon336
yeah, it think it's because they disappear and arent present in the final products or as side products.
Photon336
  • Photon336
i'm going to close this and open another one
