Value: 4 The equation of a line for Data Set 4 is y = 0.14*x + -0.0398 where y is the absorbance
values and x is the concentration in mg/mL. This was created using data from known
concentrations and absorbances. Now we can use this equation of a line to determine
the concentration of an unknown solution.
Determine the concentration of an unknown solution that has an absorbance of 0.622.
Concentration =
mg/mL. Use two sig figs in your final answer
= 1/2

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
