Question

$\sqrt[2]{9999.7 }$ pls tell

Answer 1

Step-by-step explanation:

t = ?, when x = 8O%  Therefore, a – x = 100 – 80 = 20  From above, k = 0.0102 16 min-1 t = (2.303 / 0.010216) log (100 / 20)  t = 157.58 min The time at which the reaction will be 80% complete is 157.58 min.Read more on Sarthaks.com - https://www.sarthaks.com/885154/first-order-reaction-complete-minutes-calculate-value-constant-will-reaction-complete
