Sucrose decomposes in acid solution into glucose and fructose according to the first order rate law , with t_(1//2)=3.00h . What fraction of sample of sucrose remains after 8 hours ?

The half life period of a first order reaction is 10 mins, what percentage of the reactant will remain after one hour?

In a first order reaction , the amount of reactant decomposed in the first 1 min is 1 % of its initial amount. What percent of the reactant will remain undecomposed after 1 hour from the start of the reaction ?

The decomposition of a compound follows the rate law of a first order reaction. For the initial concentration of the compound to drop to (1)/(8) and (1)/(10) th of this value , times required are t_(1//8)th and t_(1//10) respectively. Find the value of (t_(1//8)/(t_(1//10))xx10). ["given":log"10^(2)=0.3]

What is meant by pseudo unimolecular reaction. Explain with an example. 0.0625g remains from 1g of a radioactive element after 20 years of radioactive decay. Determine the rate constant and half-line (t1/2) of the reaction. How much of the element did remain after 10 years from the start.

What is meant by pseudo unimolecular reaction? Explain with an example. 0.0625 g remains from 1 g of a radioactive element after 20 years of radioctive decay. Determine the rate constant and half-life (t_(1//2) of the reaction. How much of the element did remain after 10 years from the start?

Calculate the rate constant and time required to complete 90% reaction for a first order reaction having t_(1/2) = 30 minutes. Find t_(1/2) for a 2nd order reaction K = 4.3xx10^-4 mol^-1 lit sec^-1 and initial conc. 0.24 (M).
