A chemist fills a reaction vessel with 0.770 M lead (II) (Pb²+) aqueous solution, 0.894 M bromide (Br) aqueous solution, and 0.343 g lead (II) bromide (PbBr₂) solid at a temperature of 25.0°C. Under these conditions, calculate the reaction free energy AG for the following chemical reaction: 2+ Pb²+ (aq) +2Br (aq) → PbBr₂ (s). Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule. X
