The linear form of the Arrhenius equation

The Arrhenius equation can be rearranged to a form that resembles the equation for a straight line:

lnky==(EaR)m(1T)x++lnAb

where y is lnk, m is the slope or EaR, x is 1T, and b is the y-intercept or lnA. The linearity of this equation is illustrated graphically in the image.(Figure 1)

Part B

Explanation / Answer

We get limited time to solve it. So please put other questions separately

Q-1)

Part A - Activation energy is 100-20 kJ/mole = 80 kJ/mole

Part B - The reaction is endothermic as the products have higher potential energy than reactants.

Part C - Transition state structure is 2nd one.

Part D - Reaction rate will increase with the increase in temperature as its a endothermic reaction.
