Answer #1

                 A(g)⇌2B(g)

Initial          0        1

Final          x       (1-2x)

Pressure of A = 0.4950 atm

Pressure of B = 1 - 2(0.4950) = 0.00995 atm

b)

                A(g)⇌2B(g)

Initial          0        1

Final          x       (1-2x)

Pressure of A = 5.555 * 10^(-6) atm

Pressure of B = 1 - 2(5.555 * 10^(-6)) = 0.999888 atm
