Equilibrium and Kinetics
At this point of advancements in science, chemists have a good understanding of the kinetics of reactions. They can predict the effects of changes in pH, temperature, and concentration in chemical reactions.
In a cylinder, there is a reaction mixture of hydrogen and iodine. The hydrogen and the iodine react to form hydrogen iodide.
The industrial production of ammonia is done by a process called Haber process. The reaction occurs as shown below, and is usually done in the presence of an iron catalyst.
ΔH = –92kJ
If the pressure applied to Reaction 1 is decreased, what is the most likely effect?
|A||The equilibrium will shift toward the left|
|B||The equilibrium will shift toward the right|
|C||There will be no effect on the equilibrium|
|D||The volume of the system will decrease|
Both sides of the equation have equal number of moles - two on the reactant side and two on the product side. So the pressure change will not affect the reaction in this case.
