Question

Explain in molecular terms why the Haber synthesis:

N2 + 3 H2 2 NH3
cannot proceed in a single-step elementary reaction. Select all that apply.


1)a single-step elementary reaction would require the simultaneous collision of two molecules

2)a single-step elementary reaction would require the breaking of four bonds and the formation of six new bonds

3)a single-step elementary reaction would require the simultaneous collision of four molecules

4)a single-step elementary reaction would require the breaking of five bonds and the formation of six new bonds

Answer 1

3)a single-step elementary reaction would require the simultaneous collision of four molecules
