Areaction rate increases by a factor of 655 in the presence of a catalyst at 37°c. the activation energy of the original pathway is 106 kj/mol. what is the activation energy of the new pathway, all other factors being equal?

Answer : The activation energy of the new pathway is, 89.2869 kJ/mol

Solution :

According to the Arrhenius equation,

The expression used with catalyst and without catalyst is,

where,

= rate of reaction without catalyst  = x

= rate of reaction with catalyst  = 655 x

= activation energy with catalyst  = ?

= activation energy without catalyst  = 106 kJ/mole = 106000 J/mole

R = gas constant = 8.314 J/mole.K

T = temperature =

Now put all the given values in this formula, we get:

Therefore, the activation energy of the new pathway is, 89.2869 kJ/mol

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
