Define the following term:
Pseudo first-order reaction

उत्तर
The reactions that have higher order true rate law but are found to behave as first order are called pseudo first order reactions.

The order of the reaction with respect to NO is ______. (Integer answer)
A reaction is second order with respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is reduced to half?
Higher yield of NO in \[\ce{N2(g) + O2 <=> 2NO(g)}\] can be obtained at:
[ΔH of the reaction = +180.7 kJ mol−1]
- higher temperature
- lower temperature
- higher concentration of N2
- higher concentration of O2
