According to le chatlelier's principle, a. stress on a system causes it to stop working. b. adding heat causes the equilibrium to shift to the left. c. endothermic reactions will cause an increase in solubility. d. a system will adjust to minimize the effect of an external stress placed on it. an increase in termperature [mark all correct answers] a. increases how quickly the solution can be made (for most solids dissolved in liquids). b. increases the amount of solute that can be dissolved in a solvent. c. causes the solubility to decrease for gases dissolved in liquids. d. causes the gas molecules to move faster and escape from the liquid. according to le chatelier's principle, adding more product will [mark all correct answers] a. cause equilibrium to shift to the left. b. cause equilibrium to shift to the right. c. cause more reactants to form. d. cause the equilibrium to adjust in order to relieve the stress. e. do nothing if temperature is not changed.
