Answer #1

Firstly we need to find the order of reaction wrt the reactant, C4H8. We use the first order equation and try to find the rate constant. It the rate constant comes out to be constant, that means reaction is first order.

The rate constant comes out to be constant that means reaction is first order.

    Most of the time, the rate of a reaction depends on the concentration of the reactant. In the case of second-order reactions, the rate is proportional to the square of the concentration of the reactant. Select the image to explore the simulation, which will help you to understand how second-order reactions are identified by the nature of their plots. You can also observe the rate law for different reactions. In the simulation, you can select one of the three different...
