Explanation Given: The temperature is 700 K , pressure is 0.22 atm , and time is 2.00 × 10 4 s . Explanation: The chemical reaction of decomposition of acetaldehyde is as follows: CH 3 CHO ( g ) → CH 4 ( g ) + CO ( g ) The ICE table to calculate the pressure of acetaldehyde at certain time is as follows: CH 3 CHO ( g ) → CH 4 ( g ) + CO ( g ) Initial ( atm ) 0.22 – – Change ( atm ) − x + x + x Final ( atm ) 0.22 − x x x The total pressure ( P total ) is the sum of equilibrium pressures of all the gases. P total = P CH 3 CHO + P CH 4 + P CO Here, P CH 3 CHO is pressure of acetaldehyde, P CH 4 is pressure of methane, and P CO is pressure of carbon monoxide. Substitute 0.22 − x for P CH 3 CHO , x for P CH 4 , and x for P CO in the above equation as follows: P total = ( 0.22 − x ) + x + x P total = 0.22 + x x = P total − 0.22 Calculate the equilibrium pressure of acetaldehyde as follows: P CH 3 CHO = 0.22 − x Substitute P total − 0.22 for x in the above equation as follows: P CH 3 CHO = 0.22 − ( P total − 0.22 ) = 0.44 − P total (1) t ( s ) P total ( atm ) P CH 3 CHO ( 0
