Lodine and chlorine can react according to the following equation: 12(9)+ Ch(9) 2ICK9)
At equilibrium, the concentration of ICI is about ten times higher than the concentrations of 12 or Cl2. Use
the drop-down menu to complete each statement.
At the beginning of the reaction, the forward reaction rate is
the reverse reaction rate.

A)Greater than
B)less than
C)equal to

i believe the answer is a.

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.
