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. A) 5.8 B) -5.8 C) -0.047 D) 7.2 E) 0.040

A) 5.8

Explanation:

Integrated rate law for zero order kinetic is:

Where, is the final concentration  = 0.100 M

is the initial concentration  = 0.537 M

k is the rate constant = 0.075 M s⁻¹

For 90% completion, 10% is left. so,

Applying in the values in the above equation as:-

t = 5.8 seconds

the correct answer is:

a. formation of precipitation
