1. draw a rough sketch of the energy profile for each of the following cases:

a. delta e = +10 kj/mol, ea = 25 kj / mol
b. delta e = -10 kj/mol, ea = 50 kj/mol
c. delta e = -50 kj/mol, ea = 50 kj/mol

which of the reactions will have the greatest rate at 298 k? assume the frequency factor a is the same for all three reactions.

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.  

i'm wiling to try and you : )
