An experimental data is given, `N_2(g) + 3H_2(g) rarr 2NH_3(g)`, `Delta H = -91.8 kJ//mol`
Give the significance of -ve sign of `DeltaH`.

An experimental data is given, N_2(g) + 3H_2(g) rarr 2NH_3(g) , Delta H = -91.8 kJ//mol From the abov data calculate DeltaH values for the following reactions. 2NH_3(g) rarr N_2(g) + 3H_2(g) , DeltaH = ?

Given that N_2(g)+3H_2(g)rarr2NH_3 Delta_rHtheta=-92.4 What is the sandard enthalpy of formation of NH_3 gas?

Consider this reaction: CO(g)+2H_2(g) harr CH_3 OH(g), Delta rH =- 92kJ/Mol Explain the influence of the following on the basis of Le Chateliers principle. Increase in the pressure

In Haber-Bosch process ammonia is manufacture by reacting H_2 and N_2 at 700 K and 200 atmosphere pressure. N_(2(g)) + 3H_(2(g)) harr 2NH_(3(g)) , DeltaH = -92 kJ The partial pressure of N_2 , H_2 and NH_3 are 2.09, 6.55 and 1.37 atm respectively. Calculate the value of K_P . And also explain the effect of increasing temperature on the value of K_P .

N_2(g)+3H_2(g)harr2NH_3(g) + heat How do the following factors influence the foward reaction: More N_2 is added.

Calculate the enthalpy of formation of CH_4 from the following data: C_(s) + O_(2(g)) rarr CO_2(g) DeltaH = -393.5 kJ//mol 2H_(2(g) + O_(2(g)) rarr 2H_2O_(l) DeltaH = -571.8 kJ//mol CH_4(g)+ 2O_(2(g)) rarr CO_2(g) +2H_2O_(l) DeltaH = -890.3 kJ//mol

N_2(g)+3H_2(g)harr2NH_3(g) in this equation what is the total number of moles of the reactant molecules.
