How much faster would a reaction proceed at $$25^0$$C than at $$0^0$$C if the activation energy is $$65$$ kJ?

A reaction of first - order completed $$90\% $$ in $$90$$ minutes , hence , it is completed $$50\% $$ in approximately : 

Collision frequency of a gas at $$1\ atm$$ pressure is $$Z$$. Its value at $$0.5\ atm$$ will be:

Collision diameter is least in case of:

The half-life of a zero-order reaction is 30 minutes. What is the concentration of the reactant left after 60 minutes?

For which order reaction a straight line is obtained along with $$x - axis$$ by plotting a graph between half-life $$\left( {{t_{1/2}}} \right)$$ and initial concentration $$'a'$$.

For the decomposition of $$HI$$ the following logarithmic plot is shown: $$[R=1.98\ cal/mol-K]$$
The activation energy of the reaction is about?

If $$60\%$$ of a first order reaction was completed in $$60$$ minute, $$50\%$$ of the same reaction would be completed in approximately?

The rate of a first-order reaction is $$0.04\ mol\ L^{-1}s^{-1}$$ at $$10$$ seconds and $$0.03\ mol\ L^{-1}\ s^{-1}$$ at $$20$$ seconds after initiation of the reaction. The half-life period of the reaction is:

The conversion of vinyl allyl ether to pent-4-enol follows a certain kinetics. The following plot is obtained for such a reaction.
