ACTIVITY: CHEMICAL EQUILIBRIUM Among the options, choose the best answer that will suit the question. Please provide a brief explanation. 1A. If heat is observed as products were formed means that the reaction is a. endothermic c. exothermic b. endergonic d. both b and c are correct In a laboratory experiment, a certain reaction was allowed to reach equilibrium. The reacting substances produced heat in the course of the reaction. However, one of your groupmates, unknowingly, increased the temperature of the hot plate where the flask is placed. He also added the amount of one of the reactants. 1B. If a substance that would increase the reaction's rate would have been added instead, what will happen to the equilibrium? a. shift to the left c. none of the given options b. shift to the right d. no shift 1C. Will the equilibrium re-established after one of your groupmates added an increment in the temperature? a. yes b. no c. more information required d. none of the given options 1D. What equation relates the expression of the equilibrium constant in terms of pressure and concentration? a. ideal gas equation b. van't Hoff equation c. Arrhenius equation d. Molarity 1E. If the coefficients for a reaction are all multiplied by 2, the equilibrium constant will be a. equal to Kc x 2 c. unchanged b. equal to Kc over 2 d. equal to K2
