Answer : The temperature in kelvins is,
Explanation : Given,
= 178.5 KJ/mole = 178500 J/mole
= 161.0 J/mole.K
Gibbs–Helmholtz equation is :
As per question the reaction is spontaneous that means the value of is negative or we can say that the value of
is less than zero.
The above expression will be:
Now put all the given values in this expression, we get :
Therefore, the temperature in kelvins is,
Answer:
<h2>500 J</h2>Explanation:
The kinetic energy of an object can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 1.6 kg
v = 25 m/s
We have
We have the final answer as
<h3>500 J </h3>Hope this helps you
