Equilibrium
... Chemical equilibrium can be attained whether the reaction begins with all reactants and no products, all products and no reactants, or some of both. Illustrated in the Figure 1.2 are the changes in the concentrations of H2 , I2 , and HI for two different initial reaction mixtures. In the situation d ...

Calculating Confidence Intervals and Limits
... When one considers the normal distribution curve, one can claim that 68.3% of all the values fall between x̄ ± σ where σ is the population standard deviation based on a large number (theoretically infinite) number of trials. This interval is known as a confidence interval and its limits as confidenc ...
