Sample Exercise 15.1 Writing Equilibrium-Constant Expressions
www.centrallyon.orgn by comparing the number of moles of product with the number of moles of reactants (Equation 15.15). Solve With 2 mol of gaseous products (2 NH 3) and 4 mol of gaseous reactants, (1 N 2 + 3 H 2), n = 2 –4 =2. (Remember that functions are always based on products minus reactants.) The temperature is 273 + 300 = 573 K.
