Answer:
The correct option is;
A) x = 2, y = 1
Explanation:
Here we have
....................(1)
....................(2)
..............(3)
From experiment (1), (2) it is observed that [A] is held constant and [B] is doubled of which the rate is also observed to be doubled, therefore, when you double a reactant which result in the rate being doubled, the order of the reaction with respect to the reactant is order 1, therefore, y = 1.
Similarly between reaction (2) and (3) when the concentration of the reactant B is doubled and A is held constant the rate of the reaction is multiplied by a factor of 4, therefore, the reaction with respect to that reactant is order 2, therefore, x = 2.
Therefore, the correct option is x = 2, y = 1.
Valence electrons are the electrons that are in an atom's outermost layer.
Every atom is made of protons, neutrons, and electrons.
Electrons are outside them both.
They have energy levels (number of electrons per layer)
And the number they have on the farthest layer are the valence electrons.
