For the reaction system, 2NO(g)+O_(2)(g) to 2NO_(2)(g) volume issuddenly reduced to half its value by increasing the pressure on it. If the reaction is of first order with respect to O_(2) and second order with respect to No, the rate of reaction will

Answer»

diminish to one-EIGHTH of its initial value
increase to eighth times of its initial value
increase to fourth times of its initial value
diminish to one-fourth of its initial value

Solution :`r=k[O_(2)][NO]^(2)`. When the volume is reduced to `(1)/(2)`, the conc. Will double.
`thefore` Newrate`=k[2O_(2)][2NO]^(2)=8k[O^(2)][NO]^(2)`
The new RATE increase to eight times of its initial.
