If the activation energy is 65 kJ then how much time faster a reaction proceed at $${ 25 }^{ o }C$$ than $${ 0 }^{ o }C$$?

Thermal decomposition of a compound is of first order. If $$50$$ percent of a sample of compound is decomposed in $$120$$ mins, how long will it take for $$90$$ percent of compound to decompose?

For a 1st order reaction: $$A\rightarrow Products$$; the rate of reaction at $$[A]=0.2M$$ is $$1\times {10}^{-3}$$ $$mol$$ $${L}^{-1}s^{-1}$$ reaction will be $$75$$% completed in

The activation energy of a certain uncatalysed reaction at $$300K$$ is $$76kJ{mol}^{-1}$$. The activation energy is lowered by $$19kJ{mol}^{-1}$$ by the use of catalyst. By what factor, the rate of catalysed reaction is increased?

For the equilibrium, $$Ag \rightleftharpoons B(g),\Delta H$$ is $$-40kJmol^{-1}$$. If the ratio of activation energies of the forward $$(E_{f})$$ and $$(E_{b})$$ reaction is $$(2/3)$$ then:

A reaction proceeds through the formation of an intermediate B in a unimolecular reaction
 
The integrated rate law for this reaction is?

$$SO_2CI_2\rightleftharpoons SO_2+CI_2$$ is the first order as gas raection with $$K=2.2\times10^{-5} sec^{-1}$$ at $$320^oC$$.The percentage of $$SO_2CI_2$$ decomposed on heating for 90 minutes is

The rate equation for the reaction 2A+B $$\longrightarrow $$C is rate =K[A][B].
the correct statement about this is :

A reaction requires 60 minutes and 20 minutes to complete 50% at $$27^o C$$ and $$47^oC$$ respectively. calculate activation energy of the reaction.

An adiabatic container fitted with a movable adiabatic piston (operating at 1 atm ) is filled with 2 litre of 2 M $$H_2O_2 $$(aq) solution at 300 K. If $$H_2O_2$$ dissociates following first order decay with a half life of 10 min then change in internal energy in first 20 min will be [R = 2 cal/mol K.]:
