NEED ANSWER ASAP C2H6 + O2 ---> CO2 + H2O If 15 g of C2H6 reacts with 45 g of O2, how
many grams of water will be produced?

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.

1. o2(g)as a product
