Effect of stoichiometry on the reaction rate.

Problem

On heating, J decomposes to give Y and E as products according to the equation,
12JzY+E
The rate of consumption of J (RJ) is 5times the rate of formation of Y (RY).
Calculate the value of z.
  • Your answer should be
  • a proper fraction, like 1/2 or 6/10
  • an improper fraction, like 10/7 or 14/8
