Question
For the reaction system: 2NO(g) + O2(g) → 2NO2(g) volume is suddenly reduce to half its value by increasing the pressure on it. If the reaction is of first order with respect to O2 and second order with respect to NO, the rate of reaction will
Options
A.diminish to one-eighth of its initial value
B.increase to eight times of its initial value
C.increase to four times of its initial value
D.diminish to one-fourth of its initial value
Solution
r = k[O2] [NO]2. When the volume is reduced to 1/2, The conc. will double.
∴ New rate = k[2O2] [2NO]2 = 8 k [O2] [NO]2. The new rate increases by eight times.
∴ New rate = k[2O2] [2NO]2 = 8 k [O2] [NO]2. The new rate increases by eight times.
