For each reaction, calculate ΔH°rxn, ΔS°rxn, and ΔG°rxn at 25 °C and state whether or not the reaction is spontaneous. If the reaction is not spontaneous, would a change in temperature make it spontaneous? If so, should the temperature be raised or lowered from 25 °C? d. N2(g) + 3 H2(g) → 2 NH3(g)

Video transcript

Everyone store asset 25°C. What is the standard entropy change of the reaction? The Senate entropy change of the reaction center change and gets free energy for the reaction. Or as is the reaction spontaneous. If not we're changing the temperature. Make it spontaneous. And if so should it be increased or decreased, we'll call that delta G. Of the reaction delta H. Other reaction on his T. Times Delta? S. Other reaction. I need to first find delta? S. Other reaction and this is a son times the number of moles times delta S. M. Other products finest. Some times the number of moles times Delta S. M. Of the reactant. The delta S. M. of HG 95.9. Those promote times kelvin sm of cl two Equals 223.1 mi per remote times Calvin delta S. M. Of H. G. To see up to, It goes 191.6 per mole times kelvin over a dozen s of the reaction we get one more of HG two cl 291.6 promote name's kelvin minus two malls of H G. I'm 75.9 does promote kelvin plus one more L. c. l. two 223.1 was promote how's kelvin? So for delta? S. Other reaction We get .3 Miles per Calvin Which is negative 0.183 Phil jones park Calvin. Now I need to find delta H. Other reaction and this is the sun comes. The number of moles from delta H. F. Other products minus the sun. Times the number of moles times delta H. F. Other reactant delta H. F. of HG zero kg per mole. Doctor H. F. C. L. Two. Is it okay? Just promote delta H. F. Of H. G. two. The L. Two Over 265.4. Just promote delta H. Other reaction, it's one mold of a she too. Up 10. I was negative. 265.4 Phil jones fremont one is to H. G. I'm zero kg per month. Last one month. See up to I'm zero killed gold from all without an H. Other reaction Is made of Hello jules and delta G. Other reaction. This *** 265 hill goals -25°C. those 273. Mega 0.183 jules, Calvin, delta G. Of the reaction Is Mega 211 goals. The delta G. Other reaction is negative so this is spontaneous. Thanks for watching my video and I hope what's up
