Hydrogen sulfide is oxidized by chlorine in aqueous solution. H2S(aq) + Cl2(aq)?> S(s) + 2HCl(aq) The experimental rate law is Rate = k[H2S][Cl2] ?

What is the order of reaction with respect to chlorine?
What is the order of reaction overall?
What is the order of reaction with respect to hydrogen sulfide?
The answer options are: 1st order and 2nd order

See the explanation below...

Explanation:

First of all, you have to check the balance of the given equation (this is in case of the rate law isn't given like what is in your question). Because if the equation is not balanced, the establishment of the rate law will be wrong indeed!

The equation is:
H2S(aq) + Cl2(aq)--------> S(s) + 2HCl(aq)
Hence, the rate law can be established like given:
R=k[H2S][Cl2]

So,,,,

  1. The order of reaction with respect to chlorine is ((first)).
  2. The overall order of the reaction is ((second)).
  3. The order of reaction with respect to hydrogen sulfide is ((first)).
