Question

1 What is the equilibrium constant for a reaction at temperature 89.1 °C if the equilibrium constant at 22.6 °C is 49.93?

For this reaction, Δ_rH = -21.1 kJ mol^-1 .

2 What is the Δ_rG° for the following reaction (in kJ mol^-1)?

C₆H₁₂O_{6(s, glucose)} + 6 O_{2 (g)} ⇌6 CO_{2 (g)}+ 6 H₂O _(l)

3 What is the Δ_rG° for the following reaction (in kJ mol^-1)?

2 NO_{2 (g)} ⇌N₂O_{4 (g)}

₄ What is the Δ_rG for the following reaction (in kJ mol^-1) at 298 K?

2 Si _(s) + 3 H_{2 (g)} ⇌ Si₂H_6(g)

The conditions for this reaction are:

P_H2 = 0.85 bar

P_Si2H6 = 1.03 bar

5 What is Δ_rG° for a reaction (in kJ mol^-1) which has equilibrium constant K = 3.6 x 10^-9at the temperature 45.3 °C?

Answer 1

Hello, there is some insufficient information in ques 2 and 3 as there must be given some values either of pressure or equilibrium constant or enthalpy and entropy. please check and tell me in comment box i'll be very grateful to solve the remaining 2 parts also.
