For a certain reaction, H ^ = 40 kJ and S ^ = 80 JK ⁻¹ . Find the temperature so that G ^ = 0

Options

  1. A500 K
  2. B400 K
  3. C300 K
  4. D600 K

Correct answer

A. 500 K

Step-by-step solution

Using the Gibbs free energy equation: G^ = H^ - T S^ For G^ = 0 , we get: T = H^ S^ Given H^ = 40 kJ = 40000 J and S^ = 80 J K ⁻¹ . Substituting the values: T = 40000 80 = 500 K Answer: 500 K
