Solutions for #7,8&9?

is spontaneous? why or uwhy not 7 pts. ?) If A+B-7 C, what are the? ways the cate or tie iea cti on can te desc bed ie. waied) Co pts G )

Answer 1

7.

Given,

X--> Y dG = -8 kJ/mol

Y --> Z dG = +12 kJ/mol

so for rverse reaction,

Z --> X dG = -12 + 8 = -4 kJ/mol

dG is -ve, the reaction is spontaneous

8. As we are going from less random (low entropy) NaCl(s) toa more random (higher entropy) two ions Na+ and OH- in solution. The process is spontaneous. A spontaneous system always tries to go from less random to a more random system.

9. If A+B--> C

The rate can be determines by,

keeping concentration of [A] constant, and change [B] and study effect on reaction

keeping concentration of [B] constant, and change [A] and study effect on reaction

take equal concentration of both A and B.
