Endothermic and exothermic flvs answers
WebWhether it does one or the other depends on the enthalpy change; whether it is endothermic or exothermic. If a reaction is endothermic, where heat is absorbed as the reaction progresses from reactants to products, then increasing the temperature will increase the equilibrium constant. The opposite is true if a reaction is exothermic. WebJan 30, 2024 · Answer. In the initial reaction, the energy given off is negative and thus the reaction is exothermic. However, an increase in temperature allows the system to …
