Torsional Strain

When a molecule's hydrogens are eclipsed, does that imply torsional strain on the bonds? Also, is torsional strain only prominent in planar conformations?

Reaction Mechanism Possibility [ENDORSED]

If a reaction's mechanism must agree with the experimentally determined rate law, then why does it not prove that a reaction mechanism is correct?
