In the first order reaction a → products, the initial concentration of a is 0.1 108m, and 44 s later, 0.0554m. what is the initial rate of this reaction? (initial rate-k[a]). (t %-0.693/k)

Answer : The initial rate of the reaction is,

Explanation :

First we have to calculate the rate constant of the reaction.

Expression for rate law for first order kinetics is given by :

where,

k = rate constant  = ?

t = time taken for the process  = 44 s

= initial amount or concentration of the reactant  = 0.1108 M

= amount or concentration left time 44 s = 0.0554 M

Now put all the given values in above equation, we get:

Now we have to calculate the initial rate of the reaction.

Initial rate = K [A]

At t = 0,

Initial rate = 0.0157 × 0.1108 =

Therefore, the initial rate of the reaction is,

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
