Description

98. When heating a mixture of 1.8 moles of bromine with excess butane formed two monobromo and absorb 19.0 kJ. When heating the same amount of the mixture to a higher temperature were absorbed 19.4 kJ. In both cases the bromine has reacted completely. It is known that in the formation of 1-bromobutane simple substances released by 4.0 kJ / mol lower than during the formation of 2-bromobutane. Get the thermal effects of both reactions and yield of 1-bromobutane in the second reaction, if it was in the first 38.9%. The heat of reaction can be considered zavi¬syaschimi temperature.
