QJEEM03Ch47aa: JEE Main 2003 Chemistry - Class 12 JEEM03Ch47aa Solution: For the reaction system: 2NO(g) + O 2 (g) → 2NO 2 (g) volume is …

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

Multiple Choice 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

Step-by-Step Verified Solution

r=k[O2][NO]2.

When the volume is reduced to 1/2, the conc. will double

∴ New rate =k[2O2][2NO]2=8k[O2][NO]2

The new rate increases to eight times of its initial.
