The rate constant for a particular zero-order reaction is 0.075 M s-1. If the initial concentration of reactant is 0.537 M it takes s for the concentration to decrease to 0.100 M.

Answer : It takes time for the concentration to decrease to 0.100 M is, 22.4 s

Explanation :

Formula used to calculate the rate constant for zero order reaction.

The expression used is:

where,

= initial concentration = 0.537 M

= final concentration = 0.100 M

t = time = ?

k = rate constant = 0.075 M/s

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

Therefore, it takes time for the concentration to decrease to 0.100 M is, 22.4 s

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

it's all four options.
