Document Summary
Chemical reactions: only proceed spontaneously in the downhill reaction, downhill = exergonic direction, negative delta g, energy is released, reactants, products, energetics (downhill, delta g determines whether the is going to proceed to the right. Delta g = delta h t delta s: delta g free energy change, delta h enthalpy change, t-temperature (degrees kelvin, delta s entropy change. Burning of coal: exergonic (xothermic, coal and oxygen, reactants, h2o and co2, products, heat is released, the activation energy barrier, transition state, delta g . Activation energy: delta g , energy necessary for reaction to occur, temperature is a measure of how many molecules will have achieved the activation energy, measure of the average kinetic energy of the molecules of a substance. Low temperature-low energy associated with molecules: fewer molecules have energy greater than the activation energy, how do these organisms support . Increase the amount of enzyme: to make a better catalyst.
