By which can activation energy be calculated?
1. At a constant temperature
2. At two different temperature
3. For reversible reaction
4. For volatile reaction
When a biochemical reaction is carried out in a laboratory outside the human body in the absence of an enzyme, then the rate of reaction obtained is times. The activation energy of a reaction in the presence of an enzyme is:
1.
2. P is required.
3. Different from obtained in the laboratory.
4. Data is insufficient.
The activation energy for a simple chemical reaction A → B is Ea in a forward direction. The activation energy for the reverse reaction:
1. Is negative of Ea
2. Is always less than Ea
3. Can be less than or more than Ea
4. Is always double of Ea
The temperature dependence of the rate constant (k) of a chemical reaction is written in terms of the Arrhenius equation,
k = A.e–E*/RT. The activation energy (E*) of the reaction can be calculated by plotting:
1.
2.
3.
