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, c)
2. (b, c, d)
3. (a, c, d)
4. (a, b, 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.
