Consider reaction in which reactant R is...

Consider reaction in which reactant `R` is converted into product `P`: `RtoP`. When the initial concentration of `R^(')` is `0.5M` The half life of the reaction is 20 minute. When the initial concentration is increased to 1.3 M, the half life decreases to 7.69 minute.
Q. What is the rate canstant of the reaction?

A

`0.1M^(-1)min^(-1)`

B

`0.6M^(-1)min^(-1)`

C

`0.3M^(-1)min^(-1)`

D

`1.0M^(-1)min^(-1)`

Consider reaction in which reactant R is converted into product P : RtoP . When the initial concentration of R^(') is 0.5M The half life of the reaction is 20 minute. When the initial concentration is increased to 1.3 M, the half life decreases to 7.69 minute. Q. What is the order of the reaction?

The half life period of decomposition of a compound is 50 minutes. If the initial concentration is halved, the half life period is reduced to 25 minutes. What is the order of reaction ?

Half - life period of the decomposition of a compound is "20" minutes.If the initial concentration is doubled,the half - life period is reduced to 10 mins.What is the order of the reaction?

The half period for the decomposition of a compound is 20 minutes. If the initial concentration is made twice, the half life period becomes 10 minutes. Calculate the order of reaction.

If the half-life of a reaction increases as the initial concentration of substance increases, the order of the reaction is :

At particular concentration , the half life of the reaction is 100 minutes. When the concentration of the reactant become double half life becomes , 25 minutes , then what will be the order of the reaction ?

The half-life period of a first order reaction is 10 minutes. Starting with initial concentration 12 M, the rate after 20 minutes is
