Which is the correct formation equation for ammonia?
Hear this out loudPauseThe balanced chemical equation for the formation of ammonia gas by the reaction between nitrogen gas an hydrogen gas is given. N2+3H2→2NH3.
What is the enthalpy of sublimation equal to?
Hear this out loudPause(a) Enthalpy of sublimation of a substance is equal to enthalpy of fusion + enthalpy of vapourisation. Writing in two steps, we have solid → liquid → vapour. Solid → liquid requires enthalpy of fusion.
What is the ∆ en of CH4?
Hear this out loudPauseΔrH°(303.15 K) = -889.849 ± 0.350 kJ/mol. 1.6. CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H2O (cr,l)
How do you calculate sublimation?
Hear this out loudPauseCalculate the heat of sublimation of the substance by dividing the heat absorbed by the substance, as calculated in step 2, by the mass of substance in grams. For example, if 47.5 g of substance was placed in the calorimeter, then the heat of sublimation would be 27,100 / 47.5 = 571 J/g.
How to calculate enthalpy of reaction between ammonia and oxygen?
Using the information in the table below, calculate the heat of released from the following reaction in kJ per g of NO. (Mw. of NO is 30.01 g / mol) I’m convinced the answer is c. The enthalpy of this reaction for 4 moles of NO is -905.2, to find the enthalpy for 1 mole of NO we have to divide by 4 to get to -226.3.
Where to find the thermodynamic properties of ammonia?
Thermodynamic Property TablesReader is directed to Appendix Aof this Data Book for an extensive set of Thermodynamic Property tables. For those using the thermodynamic properties for ammonia refrigeration cycle analysis, Appendix Bcontains a number of Ammonia Refrigeration Application Tables.
What is the specific entropy of ammonia NH 3?
Specific volume (v), specific internal energy (u), enthalpy (h), and entropy (s) of saturated and superheated ammonia – NH 3 – also known as refrigerant 717. For full table with Specific Entropy and Superheated Properties – rotate the screen! Ammonia Molecular weight : 17.03 g/mol.
How to calculate the vapor pressure of ammonia?
Vapor-pressure formula for ammonia: log 10P = A – B / (T − C), where P is pressure in k Pa, and T is temperature in kelvins ; A = 6.67956, B = 1002.711, C = 25.215 for T = 190 K through 333 K.
