Part B
At 700 K acetaldehyde decomposes in the gas phase to methane and carbon monoxide. The reaction is: CH3CHO(g)—CH4(g)+CO(g) A sample of CH3 CHO is heated to 700 K and the pressure is measured as 0.39 atm before any reaction takes place. The kinetics of the reaction are then followed by measurements of total pressure and these data are obtained: t(s) 0 1000 3000 7000 PTotal (atm) 0.39 0.45 0.52 0.60 Rate =- Rate=- Part B Rate= - Submit Correct APCH,CHO At APCH3CHO At APCH3CHO At Ptotal = i My Answers Give Up =9.0 × 10-4 atm-¹.s-¹PCH₂CHO² 2 =3.0×10−4s-1PCH,CHO = 4.5 x 10-4 atm-¹.s-¹] Find total pressure after 1.40x104 s.
