Answer:
To the right
Explanation:
CH₃OH(g) + heat <=> CO(g) + 2H₂(g)
According to Le Chatelier's principle, a decrease in pressure will shift the equilibrium position to the side where there is a higher volume.
From the balanced equation above,
Volume of reactant = 1
Volume of product = 1 + 2 = 3
From the above, we can see that the volume of the gasous product is higher than the volume of the gasous reactant.
Therefore, a decrease in the pressure of the system will shift the equilibrium position to the right.
Geology is the science of Earth.
Ecology is the science of relationship between an organism and its environment.
Astronomy is the science of studying astronomical objects.
Whereas, Phrenology is the study of relating the size of human skull like its size, shapes e.t.c to his/her personality. So, its not a science as there is no scientific relationship between it.
