What is the gibbs free energy at 298k for c(s) + 2h2((g) . delta h=-74.85 kj/mol, delta s is -.08084 kj/ mol
is the reaction spontaneous at 298k (room temp)? when nacl dissolves in water is endothermic butvwhen water is added it dissolves without added energy over a range of temperature why is this?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
