The reaction of methane with water to form carbon dioxide and hydrogen is nonspontaneous at 298 k. at what temperature will this system make the transition from nonspontaneous to spontaneous? the following data are valid at 298 k: ch4(g) + 2h2o(g) co2(g) + 4h2(g) substance: ch4(g) h2o(g) co2(g) h2(g) δh°f (kj/mol): –74.87 –241.8 –393.5 0 δg°f (kj/mol): –50.81 –228.6 –394.4 0 s°(j/k • mol):

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
