What specific name can be given to the following sequence of steps: $$Hg + hv \rightarrow\, Hg^*$$

$$Hg^*\, +\, H_2\, \rightarrow\, H_2^*\, +\, Hg$$

In a multistep reaction such as $$A + B$$ $$\rightarrow\, Q\, \rightarrow\, C.$$ The potential energy diagrame is shown below. What is $$E_a$$ for the reaction $$Q\, \rightarrow\, C\, ?$$

If the activation energies of the forward and backward reactions of a reversible reaction are $$E_a(f)$$ and $$E_a(b)$$, respectively. The $$\Delta E$$ of the reaction is ...........

The rate of reaction increase by the increase of temperature because:

The activation energy of reactant molecules in a reaction depends upon:

What can you say about the existence of A if the potential energy diagram for the reaction
$$A\, \rightarrow\, B$$ looks like :

In a certain reaction. $$10$$% of the reactant decomposes in one hour, $$20$$% in two hours, $$30$$% in three hours, and so on. The dimension of the velocity constant (rate constant) are:

For a hypothetical reaction: A + B $$\rightarrow$$ Products, the rate law is r = k[A]$$[B]^0$$. The order of reaction is:

The rate constant of a zero order reaction is $$0.2\:mol\:dm^{-3}h^{-1}$$. If the concentration of the reactant after 30 minutes is $$0.05\:mol\:dm^{-3}$$. Then its initial concentration would be:

90% of a first order reaction was completed in 100 min. How much time it will take for 80% completion of a reaction :
