In a chemical reaction, if Delta G is negative, it means that the reaction is: a. exergonic, and work needs to be done in order for the reaction to proceed. b. exergonic, and work can be done with the energy re
The value of delta H� for the reaction below is -482 kJ. Calculate the heat (kJ) released to the 2CO (g) + O2 (g) --> 2CO2 (g) Consider the reaction: C2H5OH (g) + 3O2 (g) \to 2CO2 (g) +3H2O ...
Depending upon the direction of heat exchange between the system and surrounding, the change in enthalpy can be either positive or negative. Answer and Explanation: For an endothermic process, heat energy is supplied by the surroundings. Hence, {eq}\rm \Delta...
$${{\mathrm{AC}}} = \frac{{\alpha \cdot \Delta I\prime + \Delta C\prime _{{\mathrm{Energy}}} + \Delta C\prime _{{\mathrm{O\& M}}} + \Delta C\prime _{{\mathrm{Material}}}{{\left( {{{\mathrm{EOC}}} \right)_{{\mathrm{reference}}} - \left( {{{\mathrm{EOC}}} ...
Step 4: Analyze the entropy (ΔS)For the reaction to be spontaneous and endothermic, we need to ensure that the term TΔS is greater than ΔH (to make ΔG negative). Assuming ΔS=135J/K: Step 5: Calculate TΔSTΔS=400K×135J/K=54000J Step 6: Substitute into the Gibbs free...
Any process for which \Delta H is negative is exothermic. Explain your answer. True or false? The size of the Delta H between reactants and products will change dramatically as the temperature changes in an endothermic reaction. True or false? Water condensing on a wind...
To start, recall that DeltaH is the change in enthalpy (energy) of a thermodynamic system from reactants to products, with exothermic reactions (releasing heat) having a negative DeltaH and endothermic reactions (absorbing heat) having a positive...
Step by step video & image solution for Enthalpy change in the following process is A+ e^(-) to A^(-) Delta H= - X kJ//"mole" Which of the following processes has enthalpy change=X kJ/mole ? by Chemistry experts to help you in doubts & scoring excellent marks in Class 12 exams...
Well, it is negative sign. You might have been given the absolute value. Sign just shows whether the reaction would be is endothermic or exothermic. But atleast, the sign for enthalpy of formatation of 2 mole of NH3 is suppose to be -92, so that when we get the standard enthalpy of...
