Explanation:
5 carbons with their substituents being bromo,chloro and dimethyl
I numbered form 1 to 5 from left to right hence the diagram above
The correct response would be A. The slowest step that determines the speed(rate) of the overall reaction.
Answer:
![2(CrO_4)^{2-} (aq) + 3N_2O(g)+ 10H^+(aq) + \longrightarrow 2Cr^{3+}(aq) + 6NO(g) + 5H_2O(l)](https://tex.z-dn.net/?f=2%28CrO_4%29%5E%7B2-%7D%20%28aq%29%20%2B%203N_2O%28g%29%2B%2010H%5E%2B%28aq%29%20%2B%20%5Clongrightarrow%202Cr%5E%7B3%2B%7D%28aq%29%20%2B%206NO%28g%29%20%20%2B%205H_2O%28l%29)
Reducing agent: nitrogen.
Oxidizing agent: chromium.

Hello,
In this case, the first step is to rewrite the undergoing chemical reaction indicating the oxidation state for each atom as shown below:
![(Cr^{+6}O^{-2}_4)^{2-} (aq) + N^+_2O^{-2}(g)+ H^+(aq) + OH^-(aq) + H_2O(l) \longrightarrow Cr^{3+}(aq) + N^{+2}O^{-2}(g) + H^+(aq) + OH^-(aq) + H_2O(l)](https://tex.z-dn.net/?f=%28Cr%5E%7B%2B6%7DO%5E%7B-2%7D_4%29%5E%7B2-%7D%20%28aq%29%20%2B%20N%5E%2B_2O%5E%7B-2%7D%28g%29%2B%20H%5E%2B%28aq%29%20%2B%20OH%5E-%28aq%29%20%2B%20H_2O%28l%29%20%5Clongrightarrow%20Cr%5E%7B3%2B%7D%28aq%29%20%2B%20N%5E%7B%2B2%7DO%5E%7B-2%7D%28g%29%20%2B%20H%5E%2B%28aq%29%20%2B%20OH%5E-%28aq%29%20%2B%20H_2O%28l%29)
In such a way, we observe the following half-reactions:
* Reduction as chromium undergoes a decrease in its oxidation state:
![(Cr^{+6}O_4^{-2})^{2-}+8H^++3e^-\rightarrow Cr^{+3}+4H_2O](https://tex.z-dn.net/?f=%28Cr%5E%7B%2B6%7DO_4%5E%7B-2%7D%29%5E%7B2-%7D%2B8H%5E%2B%2B3e%5E-%5Crightarrow%20Cr%5E%7B%2B3%7D%2B4H_2O)
* Oxidation as nitrogen undergoes an increase in its oxidation state:
![N^+_2O^{-2}+H_2O\rightarrow 2N^{+2}O^{-2}+2H^++2e^-](https://tex.z-dn.net/?f=N%5E%2B_2O%5E%7B-2%7D%2BH_2O%5Crightarrow%202N%5E%7B%2B2%7DO%5E%7B-2%7D%2B2H%5E%2B%2B2e%5E-)
In such a way, we state that the nitrogen is the reducing agent as it is oxidized and chromium the oxidizing agent as it is reduced, therefore, the balanced chemical reaction turns out:
![2(CrO_4)^{2-} (aq) + 3N_2O(g)+ 10H^+(aq) + \longrightarrow 2Cr^{3+}(aq) + 6NO(g) + 5H_2O(l)](https://tex.z-dn.net/?f=2%28CrO_4%29%5E%7B2-%7D%20%28aq%29%20%2B%203N_2O%28g%29%2B%2010H%5E%2B%28aq%29%20%2B%20%5Clongrightarrow%202Cr%5E%7B3%2B%7D%28aq%29%20%2B%206NO%28g%29%20%20%2B%205H_2O%28l%29)
Best regards.
Answer:
(K) = [H2] [Cl2] / [HCl]²
Explanation:
The equation of the reaction is given as;
2 HCl (g) ⇔ H2 (g) + Cl2 (g)
The Equilibrium constant is the ratio of the concentration of the products and reactants raised to the power of their coefficients
Products = H2 and Cl2
Reactants = HCl
Equilibrium constant (K) = [H2] [Cl2] / [HCl]²
