Using Le Chateliers principle of stress on a system at the left or to the right if heat is added to the system equilibrium, predict if the equilbrium will shift to The reaction equilibrium w heat source shift to the-- upon placing the system on a 4) in the reaction above, which way would the equilibrium shift if CaHz was used to remove the water? Circle the correct answer: Shift Left Shift Right Note: Water vapor in a reaction at equiibrium can be removed in order to pull the reaction forward. Drying agents Nke calcium hydride (Catal sodium metal and Nthium aluminum hydride LiAHe) are used to chemically destroy the water. Those drying agents are difficult to hondle and thus not used in undergraduate laboratoriesExplanation / Answer
1) Purpose of this experiment is to study the effect of change in physical variables on the equilibrium state of a reaction.
2)
Le Chatelier's principle describes what happens to a system when something momentarily takes it away from equilibrium. This section focuses on three ways in which we can change the conditions of a chemical reaction at equilibrium:
(1) changing the concentration of one of the components of the reaction
(2) changing the pressure on the system
(3) changing the temperature at which the reaction is run.
3) Given reaction involve evolution of heat during change(exothermic), so equilibrium will shift background (left) on addition of heat.
4) equilibrium shift to right (forward) because removal of water results in decrease of volume in right side.
