Determine the terminal settling velocity of spherical silicon particles in water at a teruperature of isc with specific gravity 2.40 gcm' and average diameter of 0.05 mni.

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.

The density would be 1.622
