problems involving measurements

Equilibrium Involving Chemical Systems - In reversible reactions chemical reactions take place in both the forward and backward directions. For example, the reaction between gaseous hydrogen and iodine vapours to give gaseous hydrogen iodide is a reversible reaction and may be expressed a..

. In such irreversible reactions, the reactions occur only in the forward direction. These reactions go to completion and no starting materials are left. However, reversible reactions do not go to completion. When these reactions are performed in closed containers, a stage is reached at which the r..

Suppose X = a - b Let D a and D b be absolute errors in measurements of quantities a and b, values of a and b and D X be maximum error in X. Maximum absolute error in X = Maximum absolute error in a + Maximum absolute error in b From equations (1) and (2) it is evident that, when ..

Suppose X = ab Let D a and D b be absolute errors in measurements of quantities a and b, values of a and b and D X be the maximum possible error in X. Dividing both sides by X = ab, we get are relative errors of fractional errors in values of a, b and x. Neglecting as its prod..
