The Challenge 

Nothing is easy in mathematics. It is just zero. In physics this is also easily understood as the absence of mass in space for example. For a chemist zero can be encountered in quantum mechanics when describing the probability of finding a electron at the nucleus for example Nowadays we are still trying to solve undesired problems like the accumulation of plastic waste or climate change. A target is trying to reach 0 greenhouse gas emission by 2050. Everybody knows what this means. 0 is simple to understand. Is there still room for chemistry or has it no influence at all?

The Solution

0 comes from the imagination because there is no other explanation or because common sense does not allow to fill the unknown. The objective is not to argue whether it is possible to divide by 0. But this is the type of question that arise in this problem. Other questions may be asked. What does it mean in science and in particular in chemical engineering to neglect to zero? Is an approximation always satisfying? Those questions must be asked. This is the solution.

The Mission

Find the real chemical equilibrium.
