How does the initial rate change when the concentration of NO is doubled while keeping the concentration of O 2 constant?
Options
- AIt increases by a factor of two
- BIt increases by a factor of four
- CIt decreases by a factor of two
- DIt remains constant
Correct answer
B. It increases by a factor of four
Step-by-step solution
When the concentration of NO is doubled while the concentration of O 2 is kept constant, the initial rate increases by a factor of four (from 0.096 to 0.384 mol L-1s-1)
