Question 8

Multiple Choice

Hydrogen bromide will dissociate into hydrogen and bromine gases. 2HBr(g) Hydrogen bromide will dissociate into hydrogen and bromine gases. 2HBr(g) H<sub>2</sub>(g) + Br<sub>2</sub>(g) ΔH°<sub>rxn</sub> = 68 kJ What effect will a temperature increase of 50°C have on this system at equilibrium? A) The partial pressure of hydrogen bromide will increase. B) The partial pressure of hydrogen will increase. C) The partial pressure of hydrogen bromide and bromine will increase. D) There will be no effect on the partial pressure of any of the gases. E) Need to know the initial pressure, volume, and temperature before any of the above predictions can be made. H2(g) + Br2(g) ΔH°rxn = 68 kJ
