The rate of a chemical reaction is the amount of reactant that changes to product in a specific amount of time.TrueFalse2. Collisions between reactant molecules does not always lead to the formation of product molecules.TrueFalse3. The rate of a reaction increases with increasing concentrations of reactants because you have more collisions occurring in a given time period.TrueFalse4. Which of the following changes will increase the reaction rate?increase the temperatureincrease the concentration of the reactantsincrease the energy of the collisionsdecrease the number of low energy collisionsall of the above5. A catalyst isa substance that decreases the energy of the products.a substance that increases the energy of the products.a product in a chemical reaction.a reactant in a chemical reaction.a substance that speeds up a reaction without being consumed in the reaction.6. A reaction that can proceed in either the forward or the reverse direction as written is called a __________ reaction.favoredreversiblemicroscopicminisculesolid phase7. Equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction.TrueFalse8. What is the correct form for the equilibrium constant expression for this reaction?H2(g) + F2(g) 2 HF(g) Keq = _______________9. The equilibrium expression for the reaction: TrueFalse10. For the reaction , the equilibrium constant is:2.30.150.446.7none of the above11. Le Chatelier’s principle states that when a chemical system at equilibrium is disturbed, the system shifts in a direction that minimizes the disturbance.TrueFalse12. Decreasing the amount of carbon dioxide in the reaction below will cause the reaction to proceed to the right so that equilibrium will be restored. TrueFalse13. Adding heat to an exothermic reaction will cause the reaction to remain unchanged.TrueFalse14. For the following equilibrium reaction, which cause and effect are correctly matched?CO(g) + 2H2(g) CH3OH(g) + heatremove CH3OH, shift leftadd heat, shift rightremove heat, no changeremove H2, shift leftadd CO, shift left
