For a reaction 2a (aq) + bc (aq) = ab (s) + ac (l), the order of reaction with respect to a is 2 and the overall order of reaction is 2, describe methods to increase the rate of the reaction and explain how the methods work?

As, overall order of reaction is 2 indicates the rate of reaction is only depending on concentration of A and its rate of reaction can be shown as:

R = K [A]^2

So, by increasing the concentration of A, the rate of reaction increases.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
