Considering the reaction C (s)+ O ₂(g) CO ₂(g)+393.5 ~kJ the signs of H, S and G respectively are

Options

  1. A+,-,-
  2. B-,+,+
  3. C-,-,-
  4. D-,+,-

Correct answer

C. -,-,-

Step-by-step solution

H=- ve (combustion reaction) S=- ve (spontaneous at all temperature) G=- ve (because reaction is spontaneous)

Then the enthalpy change for the give 2026For an ideal gas undergoing an isothermal change, there is 2026Ozone is formed by the reaction O _ 2(g) + O _ (g) O _ 3(g) , H = -107.2 kJ . Given O=O bond energy is 498.0 kJ mol ⁻¹ , the average bond energy of ozone is: 2026H and S for a reaction are 35.5 kJ mol ⁻¹ and 83.6 J K ⁻¹ respectively. Assuming that H and S do not vary with temperature, the reaction is spontaneous when: 2026The heat of combustion of carbon to CO ₂ is -393.5 kJ mol ⁻¹ . The heat released on the formation of 35.2 g of CO ₂ by combustion of C is: 20265 moles of a gas is allowed to pass through a series of changes as shown in the graph, in a cyclic process. The processes C A , B C and A B respectively are 20251 mole of an ideal gas is allowed to expand isothermally and reversibly from 1 L to 5 L at 300 K.
