Phosphorus pentachloride forms from phosphorus trichloride and chlorine: PCl3 (g

Question

Phosphorus pentachloride forms from phosphorus trichloride and chlorine: PCl3 (g) - Cl2 (g) rightarrow PCI5 (g) Use data in Appendix B in the textbook to calculate delta SBys . delta Ssurr . and delta Swtal for this reaction. Is the reaction spontaneous under standard-state conditions at 25 degree C? Calculate delta Says, Express your answer using one decimal place. Calculate delta Ssurr Express your answer using one decimal place. calculate delta swtal Express your answer using one decimal place.

Explanation / Answer

v(a) sin 65 = v(b) sin 37

=>v(b)=1.5 v(a)

u(a)=v(a) cos 65 + v(b) cos 37

=>6.25=v(a) cos 65 + v(b) cos 37

=>v(a)=3.845 m/sec

v(b)=5.768 m/sec
