Abstract Chemical equilibrium occurs when a reversible reaction is happening forward and backward‚ at the same time by the same amount‚ is equal. Two procedures were made. First is the Effect of Concentration on Equilibrium. The solution became orange when it was diluted with ammonium hydroxide and the solution became yellow when water was added to the solution. In the second‚ Effect of Temperature on Equilibrium‚ the solution turned into a light brown gas when it was placed in the refrigerator

1. You don’t have to be a chem whiz * Chemical engineering requires a basic understanding of chemistry‚ physics‚ math. You’re not required to memorize formulas‚ it’s more important to understand the principles and learn how to apply them to solve a problem/improve status quo. However after a few semesters‚ your brain WILLremember many formulas! * You do need to be analytical and have the ability to think critically. You must be able to look at the problem from a bigger viewpoint but
