2.
The rate of the reaction increases during the course of the reaction.
3. Every reaction has an order,
4.
A reaction with zero activation energy is practically independent of temperature.
itionis independent of the concentration of the product
Answers
2 Answer:
The rate is highest at the start of the reaction because the concentration of reactants is highest at this point. The unit of rate is simply the unit in which the quantity of substance is measured divided by the unit of time used
3 The overall order of the reaction is found by adding up the individual orders. For example, if the reaction is first order with respect to both A and B (a = 1 and b = 1), the overall order is 2. We call this an overall second order reaction.
4 When the activation energy is zero, the term e
−Ea/RT
becomes equal to 1. Hence, the rate constant becomes independent of the temperature.
When the value of the activation energy is low, the value of the rate constant is higher. Hence, the rate of the reaction is also high.
