Question

The company you work for would like to get in the business of selling hydrogen azide gas, HN3(g). One suggestion is to use a simple reaction; 3 N2(g) + H2(g)=2 HN3(g)

Data for the reaction is below.

Would you recommend that the company invest in this technique at room temp?

Invest in this technique but request additional funds to elevate the temperature of the reaction?

Invest in completely different?

Please explain and show calculations to back your decision.

Name M/(g mol^-1) Delta(f)H/(kJ mol^-1) Delta(f)G/(kJ mol^-1) Sm/(JK^-1 mol^-1) Cp,m/(JK^-1 mol^-1 H2(g) 2.016 0 0 130.684 28.824 N2(g) 28.013 0 0 191.61 29.125 NH3(g) 17.03 -46.11 -16.45 192.45 35.06

Explanation / Answer

3N2 + H2 = 2HN3

a)

dG = -16.45*2 - (3*0 + 1*0) = -32.9 kJ/mol

Would you recommend that the company invest in this technique at room temp?

Yes

since it favours products already, givne dG < 0

Invest in this technique but request additional funds to elevate the temperature of the reaction?

This could be done as well, in order to incrase rate of reaction, depends on need

Overall conclusion:

If no need to increase rate/velocity, then leave the operation as it isat Room T
