Question

When δh for a thermochemical equation is negative, that reaction is _____, while a positive value for δh is associated with an _____ reaction.

Answer 1

When Δh for a thermochemical equation is negative, that reaction is Exothermic while a positive value for Δh is associated with an endothermic reaction.

Thermochemical Equation is a balanced stoichiometric chemical equation that includes the enthalpy change, ΔH.Thermochemical Equation is a balanced stoichiometric chemical equation that encompass the enthalpy fee ΔH.In variable shape a thermochemical Equation like this . A+B→CΔH=x KJ/mol.

An exothermic system releases warmth, inflicting the temperature of the immediate surroundings to upward thrust. An endothermic manner absorbs warmness and cools the environment.

An endothermic system is in which warmness is transferred from the environment to the systems. So the device has won warmness from the surroundings. The alternate in enthalpy, delta H is fantastic for an endothermic technique. An instance could be melting an ice cube.
