Please help, Graph for the question on the Second picture,

The scientists have refilled their 2.5L vessel, maintained at 25C, with 9.5 bar of CD3. Asssuming that the rate of C2 production is the same as that given in the table for question 1, predict how many seconds it will take for the CD3 gas to be completely consumed. Your Answer: Answer 2CD3C2+3D2 Keeping a sample of CD3 in a 2.5L fixed-volume tank being kept at a temperature of 25C and an initial total pressure of 6.40 bar the scientists were able to track the production of C2, which is listed in the table below. Calculate the partial pressure of CD3 in the container when the partial pressure of C2 has reached 0.40 bar
