(5 pts) Consider the following reaction in equilibrium 2 HBr (g) H2lg) +Bog) AH-68 kJ How will each of the following changes affect the equilibrium concentrations of each chemical a) addition of HBrg) b) increasing temmperature e) increasing pressure d) decreasing volume of the reacting vessel at constant temperature e) addition of bromine ) addition of argon s) addition of catalyst

Answer 1

Agel (s) Ag (aq) + a cag) Keq = [agt] [ce] EAGI [Ag ] is solid hence its concentration is taken as 1. Keq - Cagt] [] Aglies – Agriaq) + I caq? 108x10-10 a x² da Vlog Xloo na 10341 810M Hence Cagt] = [u-] = 10341X105M
