In the context of a chemical reaction, enthalpy helps in determining whether a reaction is endothermic (absorbs heat) or exothermic (releases heat) at constant pressure. Conversely, the total energy consideration might include changes in both heat and work, offering a broader perspective on the rea...

What determines if a process is endothermic or exothermic? The sign of the enthalpy change; a negative ΔH indicates an exothermic process, and a positive ΔH indicates an endothermic process. 7 What is the significance of entropy in living systems? Entropy in biological systems is important for...
Re: Explain difference between Enthalpy of Solution and Delta G of Solution ?. « Reply #1 on: December 12, 2018, 08:53:03 AM » What determines whether the solid dissolves is ΔG of solution, not ΔH. You can easily verify that you can get both exothermic and endothermic dissolution...
endothermic reactions work is done on the system and in exothermic reactions work is done by the system so assume that there is some work for you and you do not want to do it but someone forcefully made you do that so you are unhappy hence you did that the work means work is done ...
View Solution State whether the following processes is exothermic or endothermic : H2O(l)→H2O(s),ΔH=−6.01kJ View Solution Write the relation between KpandKc for the following reactions (i) N2(g)+3H2(g)⇔2H2(g)+O2(g) (ii) 2H2O(g)⇔2H2(g)+O2(g) View Solution ...
This means that melting, vaporization and sublimation are allendothermicprocesses. They require the addition of energy or heat. The reverse processes (freezing, condensation and deposition) are allexothermicprocesses. This means that they release heat. You've probably experienced this if you get too ...
(15); and tightly contacting the heat transfer-promoting layer with the exothermic substrate and endothermic substrate so as not to form an air layer between them, wherein the heat transfer-promoting layer consists of graphite sheet and has thermo conductivity of 100-10000 W/(mK) and thickness...
The enthalpy change >0 system undergoes endothermic reactions. The enthalpy change of the <0 system undergoes exothermic reactions. The ratio of the reversible process entropy is equal to the process of absorbing heat from temperature; enthalpy is defined within the refrigerant and promote the power...
