Calculate AH for the following reaction using the given bond dissociation energies. >co,g)+2H,0(g) AH° (kJ/mol) CHg)20,g) Bond 142 О-О Н-О 459 С-Н 411 799 O O 498 С-О 358 Number ΔΗ. kJ/ mol This reaction is endothermic exothermic
N2 + 02 --> N2O3 AH = 83.7 kJ N2 + 02 ---> 2NO AH= 180.4 kJ 14N2 + O2 ---> NO2 AH = 33.2 kJ Calculate the enthalpy change for the reaction: N2O3 ---> NO + NO2
The exothermic reaction, A--> has AG<0. Which of the following statements are true AH<0 for the reaction AS must be greater than zero AS could be greater than or less than than zero the reaction is spontaneous in the reverse direction
For each chemical reaction sted in the first column of the table below, predict the sign positive or negative of the reaction entropy ?Snun 1 it's not possible to decide with the information given, check the "not enough information" button in the last column. Note for advanced students: Assume the temperature remains constant. Assume all gases and solutions are ideal reaction sign of reaction entropy O not enough information. Zn (s) + 2HCl (ag) ? Znci2 (aq) + H2 (g)...
A29. For the reaction H2(g) + I2(g) -> 2HI(g), the sign of the entropy change is a) positive b) zero c) negative; d) non-zero but cannot be determined from the given information.
