- Dixections. These questions are
based on the following sitzation. Choose the correct
options from those given below.
A collision between reactant molecules must occux with
a certain minimum energy before it is effective in
yielding product. This minimum energy is called
activation energy ( \( \left.E_{a}\right) \). Its value varies inversely with
rate constant. Moreover, larger the value of activation
energy, more is the effect of increase in temperature on
rate constant (k).
For the following reactions at a particular temperature,
\( 2 \mathrm{~N}_{2} \mathrm{O}_{5} \longrightarrow 4 \mathrm{NO}_{2}+\mathrm{O}_{2} \)
\( 2 \mathrm{NO}_{2}+\frac{1}{2} \mathrm{O}_{2} \longrightarrow \mathrm{N}_{2} \mathrm{O}_{5} \) the activation energies are
\( E_{1} \) and \( E_{2} \) respectively, then
(a) \( E_{1}E_{2} \)
(b) \( E_{1}E_{2} \)
(c) \( E_{1}=2 E_{2} \)
(d) \( \sqrt{E_{1}E_{2}^{2}}=1 \)
