Question 20 0/1 pts What is the frequency of a light wave with the wavelength of 680 nm? 'Reminder: the speed of light is 3.00 X 10 m/s

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
