Rate law expression cannot be determined from a balanced chemical equation if.
| (a) | The reverse reaction is involved. |
| (b) | It is an elementary reaction. |
| (c) | It is a sequence of elementary reactions. |
| (d) | Any of the reactants is in excess. |
The correct choice among the given is:
1. (a, b and c)
2. (b, c and d)
3. (a, c and d)
4. (a, b and d)
Hint: For elementary reaction balanced equation can be used to find rate of the reaction
Rate law can be determined from a balanced chemical equation if it is an elementary reaction. The rate law for a complex reaction find experimentally not from balanced equation.
