A sample of gas at a fixed pressure has a temperature of 300 K and a volume of 3 L. Calculate the volume if the gas is heated to 700 K.

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.

It's a
