Questions & Step-by-Step Solutions

If ΔH = 100 kJ and ΔS = 0.2 kJ/K, what is ΔG at 298 K?
  • Step 1: Identify the values given in the question. We have ΔH = 100 kJ, ΔS = 0.2 kJ/K, and T = 298 K.
  • Step 2: Write down the formula for calculating ΔG, which is ΔG = ΔH - TΔS.
  • Step 3: Calculate TΔS by multiplying T (298 K) by ΔS (0.2 kJ/K). This gives us TΔS = 298 K * 0.2 kJ/K = 59.6 kJ.
  • Step 4: Substitute the values into the ΔG formula: ΔG = 100 kJ - 59.6 kJ.
  • Step 5: Perform the subtraction: 100 kJ - 59.6 kJ = 40.4 kJ.
  • Step 6: Conclude that ΔG = 40.4 kJ.
