Hydrogenation: Hydrogenation, chemical reaction between molecular hydrogen and an element or compound, ordinarily in the presence of a catalyst. The reaction may be one in which hydrogen simply adds to a double or triple bond connecting two atoms in the structure of the molecule or one in which the addition of hydrogen results in dissociation (breaking up) of the molecule (called hydrogenolysis, or destructive hydrogenation).
Gross national product (GNP) per capita is the dollar value of a countrys final output of goods and services in a year, divided by its population. It reflects the average income of a countrys citizens.Knowing a countrys GNP per capita is a good first step toward understanding its economic strengths and needs.espite large differences in the GNP per capita of high-, middle-, and low-income countries, the trend across all countries is for the richest 20 percent of the population to earn incomes that are many times higher than the poorest 20 percent.
If one wants to use GNP (or GDP) to measure changes in overall levels of economic production from one year to the next, then using money prices as a common denominator for adding up all the disparate kinds of goods and services introduces another problem for the accuracy of the estimates -- inflation.sing the expenditure approach, you can estimate total GNP as the sum of estimates of the amounts of money that are spent on final goods and services by households (Consumption), by business firms (Investment), by government (Government Purchases), and by the world outside the country (Net Exports).
