At 25 deg. c, the second-order reaction nocl(g)no(g)+
1/2 cl2(g) is 50% complete after 5.82 hours when the
initialconcentration of nocl is 4.46 mol/l. how long will it
takefor the reaction to be 75% complete?

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.
