Which line indicates a higher reaction rate?
o
a because it has a lower activation energy
b because it has a lower activation energy
a because its agxn is much lower
b because its agxn is much lower

The correct answer is A because it has a lower activation energy.

Explanation:

Activation energy act as energy barrier during an ongoing chemical or biochemical reaction.The activation act to slow down the rate of formation of product or reaction rate.

   Lowering the activation energy increases the reaction rate.From this point of view it can be stated that high reaction rate has a lower activation energy.

B

Explanation:

o conteúdo de calor de um sistema é igual à entalpia apenas para um sistema que é constante
