Challenge An 11.75-g sample of a common hydrate of cobalt(II) chloride is heated. After heating, 0.0712 mol of anhydrous cobalt chloride remains. What is the formula and the name of this hydrate?

14.3 CONCENTRATION AND RATE LAWS - rate law – an eqn which shows how the rate depends on reactant concentrations - for the general rxn a A+ b B c C + d D the rate law generally has the form m n Rate = k [A] [B] - rate constant – the constant k; the magnitude of k changes w/ temp and therefore determines how temp affects rate - exponents m & n are typically small whole #s Reaction Orders: The Exponents in the Rate Law - exponents m & n are called reaction orders - exponents of 1 are not shown, and indicate first order - overall reaction order is the sum of the orders with respect to each reactant represented in the rat
