Answer:
The reaction rate is inversely proportional to the reaction time.
Explanation:
- The reaction rate is the change of the concentration of reactants and products with the time.
<em>∵ Reaction rate = - Δ[reactants]/Δt = Δ[products]/Δt.</em>
<em>∴ The reaction rate is inversely proportional to the time, as the reaction rate increases it will take a lower time.</em>
Answer:
e) halogens
Explanation:
Halogens -
It is the group of elements present in the group 17 of the periodic table .
Oxidizing agent -
It is the process by which the process of oxidation takes place ,
It is the tendency of an element to oxidize other element by accepting electrons and reducing itself .
In the electrochemical series ,
Halogens are placed on the top of the series , and hence have the capability to act as a very good oxidizing agent , as they can easily accept electrons other elements and reduce themselves and thereby by oxidizing the other element .
Hydrogen because oxygen gas will excuse 4 times slower than hydrogen gas !
