A first order reaction has the rate constant value of 0.10 s-1 and an initial concentration of reactant A = 0.10 M. What is the value of the half life? How long will it take for the concentration of reactant A to reach the concentration of 0.025 M?
Select one:
a. 6.93 s 13.9 s
b. 0.1 s, 10 s
c. 0.5 s, 1 s
d. 20 s, 40 s
What is true about the relationship between the rate of reaction and the reaction order for a first order process?
Select one:
a. The rate of the reaction decreases over time due to the decreasing concentration of reactants
b. The rate of the reaction increases over time due to the increasing concentration of products
c. The rate of reaction is constant over the entire life of the reaction
