1)
Every 10°C raise in temperature will
Have no effect on enzymatic activity
Increase the enzymatic activity by 50 to 100%
Decrease the enzymatic activity by 50 to 100%
Decrease the enzymatic activity by 10%
Increase the enzymatic activity by 10%
2)
Which statement about the effect of temperature on a reaction is incorrect?
The rate constant depends on temperature.
The value of Ea is temperature dependent.
The rate of reaction depends on temperature.
The rate constant is not directly proportional to the temperature.
3)
A plot of ln k against 1/T (T measured in K) for a reaction is linear with a gradient of –1.20 × 104 K. The activation energy, Ea, for the reaction is therefore:
1.44kJmol-1
99.8kJmol-1
99.8Jmol-1
693Jmol-1
4)
At about 0°C, Most of the enzymes are
Inactive
Active
Destroyed
Replicated
