DH0Cp Calc
Detailed App Info:
Application Description
DeltaH0 & Cp (mh) Calculator.
*not tested on iPhone5.
Based on "Introduction to Chemical Egineering Thermodynamics - Seventh Edition, J.M. Smith & H.C. Van Ness & M.M. Abbott - Chapter 4.
Cp (mh) denotes a mean heat capacity value specific to enthalpy calculation.
Save your time at work or Thermodynamics classes! You must be able to figure out the proper structure of the situation or problem. The App makes the calculations for you!
Choose DeltaH0 or Cp Mode through H0Cp button.
Enter #moles and Chemical (type exactly or choose from table).
Remember: CH3OH(g) should be typed as CH4O(g).
Include sets or Erase your calculation list.
Toggle between List for Calculation and the Chem table (Plus sign button on top middle).
Different Chem tables for H0 (70 chem espec!) and Cp calculations (83 chem espec!)
Beware of chemicals with the same formula and different structures! Check to see what you want to choose.
For exmple: on the H0 table we have three C7H14 chem: Heptene(g) and two cyclo (gas and liquid).
On H0 mode, Run H0 button after check your List for Calculation and get the Standard Delta H @298K for your chem reactions!
Remember to input negative number of moles for reactants and positive number of moles for products.
To go to Cp page, choose Cp mode.
On Cp mode, fill your List for Calculation and remember to leave a blank filed (Heat, T1 or T2) to solve for. T1 and T2 are solved through iterations (100 max).
You'll see the iteration error after T1 or T2 calculation.
On Cp mode you are able to see the valid temperature range for each set you included on the Calculation List.
Heat and deltaH0 in Joules, T1 and T2 in K.
R = 8.31451 J x K-1 x mol-1.
Everytime you include, erase or change mode, calculated values get red coloured font to remember you about some change you made.
Hope it helps you a lot!
