8: Generally, reaction rates will increase with _________ temperature.
Increasing
Decreasing
Static
Low
Answer:
1. Concentration (Speed is always written in terms of concentration per time)
2. Organic nature.
3.The first one. There is only one thing done here, the making of the bond of H-O. The others require atleast one bond breaking.
4. 2nd Order. There is no generation in kinetics.
5. 3. {10 raised to what is 1000.}
6. 1 {e raised to what is e}
7. 1* the number is the number = 0.36598
8. Increases (Because increasing the temperature helps breaking bonds and so helps the slowest step speed up)
