1. 2. If an exothermic reaction reaches
equilibrium, what will cooling the reaction vessel do to the
reaction? Explain your answer?
When a reaction with two reactants and one product reaches its equilibrium, what will happen to the amount of product if one reactant is removed? A+B -> С O Nothing, because the reaction has reached equilibrium O The amount of product will increase The reaction will shift to producing more reactants O The reaction will slow down the speed...

A reaction is said to be ________ if the bonds formed during the reaction are stronger than the bonds broken. A) exergonic B) endergonic C) endothermic D) exothermic E) spontaneous I know the answer is exothermic but I'm confused as to why. Wouldn't having stronger bonds formed than bonds broken mean that delta_H is positive since the enthalpy on the products is bigger than the reactants thus making it endothermic?
Chemical energy stored in the reactants is released as heat when the reaction is exothermic. For...
Chemical energy stored in the reactants is released as heat when the reaction is exothermic. For an exothermic reaction, the enthalpy change for a reaction is negative. Enthalpy, represented as H, is the heat content of a system. As it is a state function, it depends on the state of the system; hence, it is calculated in the form of change in heat content. Heat change, or enthalpy change, is represented as ΔH; ΔH is a measure of the heat...
