In simple terms, rvalues measure the effectiveness of insulation and a higher number represents more effective insulation. Chemistry definition of gas constant r the gas constant or r is an essential constant in the ideal gas law. The higher the rvalue, the greater the insulation performance. The objectives of this lab are to experimentally determine the value of the gas constant, r, and to practice using the gas laws to solve a variety of problems. Values of the universal gas constant r in various units. Chemistry 2e is designed to meet the scope and sequence requirements of the twosemester general chemistry course. Thus, the value of the gas constant ultimately derives from historical decisions and accidents.
