JEE Main Chemistry question
For a reaction between A and B, the initial rate of reaction is measured for various initial concentrations of A and B. The data provided are [DCE 2009]
| | | | Initial reaction rate | |---|---|---|---| | 1 | 0.20 M | 0.30 M | | | 2 | 0.20 M | 0.10 M | | | 3 | 0.40 M | 0.05 M | |
The overall order of the reaction is
Answer: (A)
Solution
Comparing experiments 1 and 2 ( fixed, changed, rate unchanged): order with respect to B is 0. Comparing experiments 2 and 3 ( doubled,
