a container with 2.5 mol of oxygen gas at 300 k is placed on a large stone slab with a temperature of 600 k. the stone slab is so large that its temperature does not change. the gas is heated at constant pressure until it reaches equilibrium. assume that the entropy change of the container itself is negligible. A) What is delta Sgas as the system comes to equilibrium?B) What is delta Sstone as the system comes to equilibrium?C) What is delta Stotal as the system comes to equilibrium?
