Chemical Kineti...

A substance having initial concentration (a) reacts according to zero order kinetics. How much time will the reaction take to reach the completion?

If the initial concentration is reduced to 1/4th in a zero order reaction, then the time taken for half the reaction to complete:

At 400K, the half-life of a sample of a gaseous compound initially at 56.0 $$kPa$$ is 340s. When the pressure is 28.0 $$kPa$$, the half-life is 170s. The order of the reaction is:

$$N_{2}O_{2} (g)\rightarrow2NO$$   is  a first-order reaction interms of the concentration of $$N_{2}O_{2} (g)$$  .Which of the following is valid, $$[N_{2}O_{2} ]$$  being constant?

The time required for the completion of first order reaction is:

The reaction $$L\rightarrow M$$ is started with $$10.0\ gm$$ of $$L$$. After $$30$$ and $$90$$ minutes, $$5.0\ gm$$ and $$1.25\ gm$$ of $$L$$ respectively are left. The order of the reaction is:

For the reaction A $$\rightarrow $$ B it has been found that the order of the reaction is zero with respect to A. Which of the following expressions correctly describes the reaction?

$$SO_{2}Cl_{2} \rightarrow  SO_{2}+Cl_{2}$$ is a first order gas reaction with $$k=2.2\times 10^{-5}\sec^{-1}$$ at $$320^o C$$. The percentage of $$SO_{2}Cl_{2}$$ decomposed on heating for 90 minutes is:

Which equation represents the time to complete 90% of first order reaction?

At room temperature the reaction between NO and $$O_{2}$$ to give $$NO_{2}$$ is fast while that of between CO and $$O_{2}$$ is slow. It is because:
