Reaction pathway

1) Is Ea positive or negative for each of the following:

a) A $\rightarrow$ B

b)B $\rightarrow$ C

c)A $\rightarrow$ C

2) Which step in the reaction A $\rightarrow$ C has the greatest Ea?

Answer 1

Answer #1

Answer -

Ea is the activation energy.

a.The value of Ea is negative as the product B have high energy compared to reactnat A. Hence the sign of the Ea is negative.

b.The value of Ea is positive as the product C have low energy compared to reactnat B. Hence the sign of the Ea is positive.

c.The value of Ea is positive as the product C have low energy compared to reactnat A. Hence the sign of the Ea is positive.

2.

A---> B have gratestactivation energy, as there is largest energy difference between the product of reactant and reactant.
