Which of the following are true for the following two reactions at 25°c: reaction 1: no(g) + o(g)  no2(g) reaction 2: no2(g) + no2(g)  n2o4(g) hint: no2 has the structural formula ono, and n2o4 has the structural formula o2nno2 i: for reaction 1, the following collision has the correct orientation to react: no   o ii: for reaction 2, the following collision has the correct orientation to react: o2n   no2 iii: assuming activation energies are equal, reaction 1 is predicted to have a higher rate than reaction 2 a) only i b) only ii c) i and iii d) ii and iii e) i, ii, and iii
