The article “Uncertainty and Climate Change” considers three scenarios, labeled A, B, and C, for the impact of global warming on income. For each scenario, a probability mass function for the loss of income is specified. These are presented in the following table.
a. Compute the mean and standard deviation of the loss under scenario A.
b. Compute the mean and standard deviation of the loss under scenario B.
c. Compute the mean and standard deviation of the loss under scenario C.
d. Under each scenario, compute the probability that the loss is less than 10%.
What is the equilibrium composition of this system at that T and P if you start with a 1 mole of H2O and 2 moles of CO? Assume the heat of reaction is not a function of temperature.
The “water-gas” shift reaction is catalyzed by an iron oxide/chromium oxide catalyst at 700 K and 2 bar. H2O + CO ? CO2 +H2
