The reaction of A and B occurs according to the reaction:   A + 2B + C → D + E   The reaction time is determined by a color change marking the complete consumption of reactant B. The following data was collected for this reaction.   Trial time (s) A (M) B (M) C (M) 1 100 2.50 × 10−2 2.50 × 10−2 2.50 × 10−2 2 96 2.50 × 10−2 2.50 × 10−2 5.00 × 10−2 3 67 2.50 × 10−2 3.75 × 10−2 2.50 × 10−2   (a) What is the rate for trial 3?

Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If H,O, is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 7 seconds of the reaction? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. 미

Can you help me correcting this questions  in the picture with the notes below please? Notes: In question 1a, the rate law is fine but should have partial pressures, not concentrations. In 1b, the units of the answer are incorrect; they should have "atm" in it. Hint: in the denominator of the calculation is atm^3.

Consider the reaction: H2 (g) +I2 (g) → 2 HI (g) A chemist performed an experiment and monitored the concentration of I2 during the course of the reaction. The red line in the graph below represents the results obtained. Which line in the plot would best represent how the concentration of HI changes during the course of the reaction?
