MCQ
If $R = K{[NO]^2}[{O_2}],$ rate constant may be increased by
- ✓Increasing temperature
- BDecreasing temperature
- CIncreasing concentration of ${O_2}$
- DIncreasing concentration of $NO$
✓
Answer
Correct option: A.
Increasing temperature
a
According to Arrhenius Rate Equation:
According to Arrhenius Rate Equation:
$k = Ae E ^{- E _a / RT }$
Rate Constant only depends on Pre-Exponential Factor, Activation Energy, Ideal Gas Constant, Temperature.
On Increasing Temperature, Rate Constant can be increased.
