Disturbance Equilibrium: How to Shift Right Equilibrium: How to Shift Left Concentration Temp: Endothermic Temp: Exothermic Pressure: More mol of reactant Pressure: more mol of product

An increase in product concentration drives the reaction towards more reactants. True O False

The choices are: Reversible reaction, Le Châtelier’s principle, and Chemical equilibrium

* Question Completion Status: QUESTION 1 Consider the following reversible reaction at equilibrium: 3 H2(g) + N2(g) → 2NH3(g) + heat Which of the following changes will shift the equilibrium towards the reactants (left side)? O Decreasing the amount of NH3. O Adding a catalyst to the system. O Decreasing the volume of the system. O Decreasing the temperature. O Decreasing the amount of H2.

At equilibrium, what is the rate of production of reactants compared with the rate of production of products? *       much higher       higher       the same       lower

The following figure is humorous but it emphasizes an important characteristic of either a chemical or physical equilibrium. What is it? We're back! I'm sure glad they evaporated! Then I'm getting out of here! A) Equilibrium occurs when all processes come to an end. B) Equilibrium is temperature independent. · C) Equilibrium is reached when the number of reactant and product molecules is the same. D) Equilibrium is dynamic. E) Equilibrium depends on where you start the process. rch inort sc delete 8. backspa K pause

true or false? If a reversible reaction at equilibrium is exothermic and the tempature is raised the concentration of the products will increase
