Consider this reaction: H,CO, (aq) H,0 (aq)+CO, (aq) At a certain temperature it obeys this rate law. rate = (0.067 s ")[H,CO,] Suppose a vessel contains H,CO, at a concentration of 0.870M. Calculate how long it takes for the concentration of H, CO, to decrease to 9.0% of its initial value. You may assume no other reaction is important. Round your answer to 2 significant digits.

What is the order of the reaction with respects to B and why is that? Please explain .

None

Captain Marvelibrium discovered a figure with data frorh an experiment left by Le Châtelier Flipdime. Consider the following data where A andB are mixed at initial concentrations indicated. Upon reacting the concentrations change a can be read from the plot. The reaction is A(g) + B(g) = C(g). C Time (s) Based on figure, calculate the value for Ke for the reaction.
