Now to determine deltaH for the combustion of phosphine I first need the enthalpy of formation for products and reactants right? So I need the chemical equation which I think is: 4(PH3) + 8(O2) --> P4O10 + 6(H2O
How to calculate enthalpy of combustion What amount of heat, in kJ, would be involved in condensing 15.8 g of CH3OH? (delta H vap = 38.0 kJ/mol) If you have 1.06 grams of ice, how much heat, in joules, would you need to provide to completely melt the ice at zero degrees Celsius...
How do you calculate entropy from enthalpy? How to calculate enthalpy of combustion Find the molar enthalpy of vaporization for a substance, given that 3.21 mol of the substance absorbs 28.4 kJ of energy as heat when the substance changes from a liquid to a gas. Given that water has a mola...
In the (1)reaction Engineering module , I uploaded the CHEMKIN thermo and transport file to set up the temperature dependent specific heat capacity, entropy, enthalpy and transport properties(include viscosity). And in the (2)laminar flow , I have to set up fluid propert...
Enthalpy of Reaction:For a reaction to occur, the system will either release energy through heat or absorb energy in the process. However, in the process, there will still be an energy requirement that is known as the activation energy. T...
Now, you can do this a number of different ways depending on the resources you have available: The easiest and most accurate way would be to look up the enthalpy of each component at 298 K and 400 K and just take the difference to find ΔHi for each component, then refe...
Although I do not know the enthalpy of combustion of crude oil, assuming electricity is to replace 4.5 Mb of gasoline to power cars, I get: enthalpy of combustion of gasoline: 130 MJ / gallon 130 MJ/gal * 4.5 Mb * 42 gal/b = 24.6 x 1015 J Because an electric car is 3 times ...
Without spending a huge amount of time talking about how the human person is cooled through evaporation and controlling that evaporation rate through the total heat content and enthalpy of the air, it is very hard for me to effectively communicate how little impact the efficiency difference of the...
If the total internal energy, total pressure and the total volume of a phenomenon are given, then by using the sum of the energy and the product of the pressure and volume is generally used to calculate the enthalpy. The general expression of the enthalpy is shown below, ...
Answer to: How can chemists use the properties of a solute to predict if an enthalpy change of solution will be exothermic or endothermic? By...
