Consider the following hypothetical reaction: A+BC Calculate the average rate of the reaction on the basis of the following information: a. Pure A,B, and C are mixed together at concentrations of A+B=0.400M, C=0.150M. After 6.00minutes, the concentration of C is 0.418M. b. Pure A, and B are mixed together at same concentrations of 0.361M. After 7.00minutes, the concentration of A is found to be 0.048M.
Consider the following hypothetical reaction: A+BC Calculate the average rate of the reaction on the basis of the following information: a.

In Chapter 3, we discussed the conversion of biomass into biofuels. One important area of research associated with biofuels is the identification and development of suitable catalysts to increase the rate at which fuels can be produced. Do a web search to find an article describing biofuel catalysts. Then, write one or two sentences describing the reactions being catalyzed, and identify the catalyst as homogeneous or heterogeneous.
