At 300 ~K , a gaseous reaction A B + C was found to follow first order kinetics. Starting with pure A , the total pressure at the end of 20 ~min was 100 ~mm of Hg . The total pressure after the completion of the reaction is 180 ~mm of Hg .

Question

At 300 ~K , a gaseous reaction A B + C was found to follow first order kinetics. Starting with pure A , the total pressure at the end of 20 ~min was 100 ~mm of Hg . The total pressure after the completion of the reaction is 180 ~mm of Hg . The partial pressure of A (in mm of Hg ) is

Quantrex Academy · Accepted Answer

Correct answer: C. 80

At the end of the reaction, A completely converted into products, so the pressure of the products after completion of the reaction = P _ i Partial pressure of A , P _ A = p _ i - x aligned &=(180-100) atm &=80 ~atm aligned
