Thus wrote Charles Darwin on the twenty-second and twenty-fourth of October 1873.[1] At first reading this passage appears rather incongruous, but actually it reflects the true nature of the resurgence of evolution in the Nineteenth Century: but to see this, it behooves us to look back further in history; back to the root of evolution as an idea ...
May 9, 2014. Exothermic reactions are spontaneous because the product created by an exothermic reaction is the most stable product. Exothermic reactions release heat or energy. The more energy something has, the more unstable it will be. Therefore kinetics determines that the most stable product will dominate and as a result exothermic reactions are spontaneous to produce a stable product.
Which of the following combinations will result in a reaction that is spontaneous at all temperatures? Select one and explain why it is correct the other choices are not correct: a. positive enthalpy change and positive entropy changeb. positive enthalpy change and negative entropy changec. negative enthalpy change and positive entropy changed.
