Explanation
Units of 1st rate constant order reaction are sec−1 and for zero order reaction, these are mol L−1 sec−1 i.e. M sec−1 .
(1) by definition.
2N2O5 → 2N2O4 + O2 is bimolecular but of first order.
The activation energy for the reverse reaction can be less than or more than Ea depending upon whether the reaction is endothermic or exothermic.
Ea is energy of activation.
Rate of reaction decreases with time, increases with concentration of reactant and increases with increase in temperature.
The rate of reaction is same as expressed in terms of any reactant or product.
Rate = k[A]2[B]
Concentration in moles L-1 are highest in (2).
As rate = k [RCl], the rate is halved when [RCl] is halved. Also the rate increases with increase of temperature.
Activation energy of a particular reaction is constant at constant temperature.
the activation energy of the reaction is large
(p + q) = (m + n) or (p + q) ≠ (m + n)
