This is a industrial reaction for benzene production: C 6 H 5 CH 3 + H 2 --> C 6

Question

This is a industrial reaction for benzene production: C6H5CH3 + H2 --> C6H6 + CH4

Which statements are correct about this reaction?

a) This is a balanced equation

b) To calculate the percentage atoms economy of the reaction, you take the molecular mass of the products and divide by the molecular mass of reactants, and then multiply by 100

c) To calculate the percentage atoms economy of the reaction, you take the molecular mass of benzene over the reactants and divide by the molecular mass of reactants, and then multiply by 100

d) You could use the byproduct of this reaction as an energy source

e) This is a redox reaction

Explanation / Answer

a) if you count the number of ieach atom inboth sides they are the same. Then yes this is a balanced equation.

The percent atom economy is measured by diving the mass of atoms in the desired product over the mass of atoms in the reactants and the multiply by 100. Then i do not see that b nor c are true because in c it could b it you do not divide the benzene twice.

d) methane is used as fuel, benzen no.

d) as you can see in the reactants side we have the hydrogen in elementary form. (H2) in this form it has oxidation state = = . In the products side we see that in the two molecules hydrogen has oxidation state of +1 then yes this is a redox reaction.
