Consider the following equation: Ag+ (aq) + CI-(aq) → Ag+CI- (s) ; ∆H = _65.7 kJmol-1. From the equation, it can be deduced that

Answer Details

The given equation is a chemical equation that represents a reaction between silver ion (Ag⁺) and chloride ion (CI^-) to form silver chloride (Ag⁺CI^-). The value of enthalpy change (∆H) is given as -65.7 kJmol^-1, which indicates that the reaction is exothermic, i.e., heat is evolved during the reaction. Thus, the correct option is "a solid is formed and heat is evolved."
