This two step mechanism has been proposed for the decomposition of nitrous dioxide, N,0. Step 1: N20 (9) N269) + (0)
Step 2: N206+09) - N279) + O2(g)
Overall: 2N204) - 2N20 * 02(9)
Explain how the reaction progress diagram indicates the presence of any intermediates present in the reaction mechanism.
es.)
A)
The existence two peaks in the reaction path between the reactants and
products indicates an intermediate is formed in the mechanism.
B)
C)
The presence of a free energy minimum in the reaction path between the
reactants and products indicates an intermediate exists in the mechanism.
The lower first peak and activation energy in the reaction path between
the reactants and products shows there is an intermediate in the reaction
mechanism
The second peak with higher activation energy in the reaction path
between the reactants and products proves there is an intermediate in the
reaction mechanism.
D)

Which of the following represents a balanced nuclear equation showing bismuth-212 undergoing alpha decay followed by beta decay? (2 points) superscript 212 over subscript 83 bi yields superscript 4 over subscript 2 he + superscript 208 over subscript 81 tl yields x−superscript 208 over subscript 82 pb + superscript 0 over subscript -1 beta superscript 212 over subscript 83 bi + superscript 0 over subscript -1 beta yields superscript 4 over subscript 2 he + superscript 208 over subscript 81 tl yields x−superscript 208 over subscript 82 pb superscript 216 over subscript 85 as yields superscript 4 over subscript 2 he + superscript 216 over subscript 85 as yields superscript 216 over subscript 85 pb + superscript 0 over subscript -1 beta superscript 212 over subscript 83 bi yields superscript 0 over subscript -1 beta + superscript 208 over subscript 81 tl yields superscript 208 over subscript 82 pb + superscript 4 over subscript 2 he
