Answer : This reaction occur spontaneously at temperature above in kelvins is, 340 K
Explanation : Given,
= 17 KJ/mole = 17000 J/mole
= 50 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, this reaction occur spontaneously at temperature above in kelvins is, 340 K

The answer to the question stated above is letter a. run at highest <span>speed.
</span>Jumpering out the resistors in a resistance-controlled three-speed fan will cause the motor to <span>run at highest speed. If resistors are jumpered, the three-speed fan will over speed and probably burns out.</span>
Answer:
Electromagnetic
Explanation:
All electromagnetic waves have a certain energy and frequency, and since they are a form of radiation, they can propogate even through space.
