Working on a problem and can't figure out how the book rearranged this problem to get the following: 0.76= x/0.0200-x then, the book rearranged to solve for x... x= 0.0200 X 0.76/ 1.76 I don't understand how 1.76 was obtained? I see that you cross multiply to get 0.020...

A 0.100 mol sample of H2S is placed in a 10.0 L reaction vessel and heated to 1132°C. At equilibrium, 0.0285 mol H2 is present. What is the value of Kc at this temp? 2 H2S(g) 2 H2(g) + S2(g After I do my calculations, I get Kc= (0.0057)2 X (0.00285)/(0.0043)2 and get 5.03 ...

The main reason for the increase in reaction rate with temperature is that: The activation energy increases rapidly with temp (I think it is this one) A 10 C temp rise results in the rate doubling heats acts as a catalyst or The fraction of high-energy molecules increases expe...
