This resource turns effect of concentration into a complete, ready to use review for Grade 9-12 chemistry, covering the same NGSS standard from three different angles.
Among the ninety questions, students will see prompts such as "In the equilibrium reaction N₂ + 3H₂ ⇌ 2NH₃, what happens if the concentration of NH₃ is decreased?", "If the concentration of reactant A decreases, what shift will occur in the reaction A + B ⇌ C?", and "When the concentration of all reactants is doubled, what is the effect on the equilibrium position?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a complete NGSS aligned chemistry unit. The unit also covers What Is Chemical Equilibrium, Forward and Reverse Rates, Le Châtelier’s Principle, Effect of Temperature, Effect of Pressure, and Catalysts and Equilibrium, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 chemistry classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-PS1-6.
