Consider a biochemical reaction under standard conditions. The change in enthalpy is -7 kJ/mol and the change in entropy is -25 JK^-1 mol^-1. Without doing any calculations, can you determine if the reaction is spontaneous? Calculate delta G^degree' for the reaction at 5 degree C. Is the reaction spontaneous or not? Why or why not? If not, does raising the temperature make the reaction more likely to be spontaneous, or less likely to be spontaneous?

Six kilomoles (12.095kg) of hydrogen gas (H2) at S.T.P. (Standard Temperature & Pressure) expands isobarically to twice its volume. What is the final temperature of the gas? What is the expansion work done by the gas? How much does the internal energy of the gas change? How much heat enters the gas during the expansion?

What is the nuclear reaction occurring? Light nuclei (such as hydrogen) under high temperature combine to form a larger single nucleus (such as helium). An atom of one element is converted to an atom of another element. Like when a spontaneous emission of a beta particle causes a atom of lead-214 to change into bismuth-214. A heavy nucleus (such as the U-235 nucleus) splits into two or more parts. What are the differences between how a coal power plant and...
