Acids' Alkalis and PH

This will lead to a decrease in the concentration of H+(aq). According to Le Chatelier's principle, the reaction will shift to the side that opposes this change. This means that the reaction will shift to the right.
The reaction is exothermic. According to Le Chatelier's principle, a decrease in the temperature of the equilibrium mixture causes the reaction to shift to the side that opposes that change. This entails that the reaction will shift to the right.
Adding a catalyst to the above reaction causes the forward and reverse reaction rate constants to be increased by the same amount. This means that equilibrium will be reached more quickly but will have no effect of the position of equilibrium (Brown, LeMay and Bursten, 1991).
Kc is the ratio of the forward and reverse reaction rate constants. As seen above, the catalyst will increase these reaction rates by the same amount. There will hence be no change in the value of Kc (Brown, LeMay and Bursten, 1991).
When ammonia is dissolved in water, it accepts H+. ...Show more


2. For each equilibrium system in question 1, above, predict the change that will occur to the position of equilibrium when the stated change occurs. Justify each prediction by considering 'le Chatelier's Principle'
According to 'Le Chatelier's Principle', if a system at equilibrium is disturbed by a change in temperature, pressure, or the concentration of one of the components, the system will shift its equilibrium position so as to counteract the effect of the disturbance (Brown, LeMay and Bursten, 1991)…

The Effects of Temp & PH on Enzymes
This is because they have unique active sites into which only specific substrates can fit. Enzymes bind temporarily to one or more of the reactants of the reaction they catalyze and in doing so; they lower the amount of activation energy needed and thus speed up the reaction (Groves, 1997).

Acid Rain and Alkalinity of the Lakes in Canada
Surface and soil waters such as lakes and streams receive acid from a variety of natural sources. Natural sources of acids is obtained by decomposition of animals and plants, forest fires, volcanoes, which produce sulfur oxide/sulfuric acid. Carbonic acid is formed by carbon dioxide in the air, and the lightning bolts changes nitrogen molecules in air to nitrogen oxides and nitric acid.
