I calculate the change in thermal energy of the following reaction h2 (g) br2 (g) ® 2hbr (g) determine energy bond hh = 431 kj / mol, h-br = 366 kj / mol and br-br = 193 kj / mol, this reaction is endothermic or exothermic out how much .
"Calcuate the change of heat energy of the following reaction H2 (g) Br2 (g) ® 2HBr (g) specifies that bond energy H-H = 431 kJ/mol, H-Br = 366 kJ/mol and kJ/mol Br-Br = 193, this reaction is endothermic, or spit out heat? .
Go to calculate the change of the power of the heat of reaction following H 2 (g) Br 2 (g) 2 HBr® (g) whether energy obligation H - H=431 kJ/mol, H - Br=366 kJ/mol and Br - Br=193 kJ/mol this reaction is a heat-shock or discharge the heat out how much?
