If you know the rate of consumption of a reactant in a chemical equation how can you calculate the rate of formation of a product? Give me an example of a problem and solve it.
-
you compare the coefficients of the balanced equation
example...
4 AB + 6 CD ---> 2 A2D3 + 1 C6B4
if the rate of consumption of AB = x
the rate of production of C6B4 is 1/4 x
the rate of production of A2D3 is 2/4 x
another example..
2 H2 + 1 O2 ---> 2 H2O
- d[H2] / dt = + d[H2O] / dt = - 2 x d[O2] / dt
notice the opposite signs? - because concentration is decreasing.. + when concentration increases
