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

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

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

    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

    you mean 2-step reaction

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

    well seems to be no intemediate here ??

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

    usually because it's unstable

    sometimes it can be detected though

    @rushwr @Shalante thoughts?

  20. Shikamaru11

    so Cl* and OH* are intermediates then

    @Shikamaru11 I think OH is definitely an intermediate

    Guys they both are intermediates looked up the answer

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