Answer: II. The catalyst provides a new pathway in the reaction mechanism.
III. The catalyst speeds up the reaction.
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and more molecules convert to products.
The catalyst itself does not take part in the chemical reaction and gets regenerated as such at the end of the reaction without getting consumed.
It is true that when the outer electrons of substances are removed, they become statically charged. The correct answer is True.
Answer:
Follows are the solution to these question:
Explanation:
Given equation:
In this equation:
gives 
so,
gives= 
similarly:
gives
So, 
gives = 
Its limited reagent is =
The amount of 
molecules were formed = 4.
and the amount of 
excess molecules are= 1
The correct answer is the first one
