Question

Given that a reaction absorbs energy and
has an activation energy of 50 kJ/mol.
which of the following statements are
correct? (1) The reverse reaction has an
activation energy equal to 50 kJ/mol. (2)
The reverse reaction has an activation
energy less than 50 kJ/mol. (3) The
reverse reaction has an activation energy
greater than 50 kJ/mol. (4) The change in
internal energy is less than zero. (5) The
change in internal energy is greater than
zero.
O (1) and (4)
O (2) and (4)
O (3) and (4)
(2) and (5)​

Answer 1

Answer:

Hello buddy,

lemme explain,

We know ki Dell.H =Ef -Eb

or Eb = Ef - Dell.H

So the energy of Activation for it's backward direction depend upon the heat of reaction and it can be greater or less than

50Kj/mol.

So ur answer is 2 and 4

And dear if it helps u

then thank u so much
