State whether the following is true or false.
The order of a reaction can be predicted from its balanced chemical equation.

  • A.False only at small scales
  • B.True
  • C.False
  • D.True only at large scales

Answer: C

Only for an elementary step do the coefficients give the order, and most overall reactions proceed through several steps. Order is an experimental result rather than something read off an equation. Only elementary steps are the exception.
