The following chemical equation is not balanced: c3h8 + o2 co2 + h2o when this chemical equation is correctly balanced, what is the coefficient of the carbon dioxide molecule? a. 1 b. 2 c. 3 d. 4

the product of the pressure and volume is also constant

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
