Plotting, therefore, the difference in rate at two fixed pressures of hydrogen against temperature gives the variation with temperature of the homogeneous part of the reaction. This variation is partly due to the change with temperature in the concentration of the sulphur vapour... 

We model hydrogen adsorption by attaching a hydrogen atom to the surface atom (terminal carbon) an extra band is produced, the stretching mode of hydrogen against the surface, C—H. This is usually a high... 

The lifetime of the 2p level of hydrogen against spontaneous decay by electric dipole radiation is l S96 10 s. Estimate the radiative lifetimes of the 2p levels of both singly-ionized helium and doubly-ionized lithium. 

The last example presented in this section deals with the pitting corrosion of Fe in CIO solutions. Perchlorate is less known as an aggressive ion but reveals some unique and remarkable characteristics with regard to pitting corrosion. For example, the critical pitting potential (1.46 V against a standard hydrogen electrode (SHE) for Fe/1 M NaClO ) can be measured with an accuracy of less than 4 mV [61] which is very unexpected if compared to... 

Hydrogen chloride. Method 1 from concentrated sulphuric acid and fused ammonium chloride). The most convenient procedure is to allow concentrated sulphuric acid to react with lumps of fused ammonium chloride in a Kipp s apparatus. The gas may be dried by passage through a wash bottle containing concentrated sulphuric acid the latter should be followed by an empty wash bottle or flask as a precaution against sucking back of the contents of the reaction vessel.

When standardizing a solution of NaOH against potassium hydrogen phthalate (KHP), a variety of systematic and random errors are possible. Identify, with justification, whether the following are systematic or random sources of error, or if they have no effect. If the error is systematic, then indicate whether the experimentally determined molarity for NaOH will be too high or too low. The standardization reaction is...
