After 20 min, a reactant has decomposed to 85 % of its original concentration. Which order would the reaction need to be to allow you to solve for the rate constant, k , with only this information?

Answer : The value of rate constant is,

Explanation :

First we have to calculate the rate constant, we use the formula :

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

where,

k = rate constant  = ?

t = time passed by the sample  = 20 min

a = let initial amount of the reactant  = 100 g

a - x = amount left after decay process = 100 - 85 = 15 g

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

Therefore, the value of rate constant is,

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
