A zero order reaction is 20% complete in 20 minutes. Calculate the value of the rate constant. In what time will the reaction be 80% complete?

उत्तर
1. A = 100%, x = 20%, Therefore, a – x = 100 – 20 = 80
For the zero order reaction k = `("x"/"t")` ⇒ k = `(20/20)` = 1
Rate constant for a reaction = 1
2. To calculate the time for 80% of completion
k = 1, a = 100, x = 80%, t = ?
Therefore, t = `("x"/"k") = (80/1)` = 80 min
