We have a 100ml one molar agno3 solution. which of the following would make the lamp light much higher?
1)0.02mol nano3
2)0.03mol nacl
3)0.02mol bacl2
4)0.03mol mg3(po4)2
why? description to me.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
