FIRST Step Consider the formula

G id = (x 1 \cdot G1 id + x 2 \cdot G2 id) + [R] \cdot T \cdot (x 1 \cdot \ln (x 1) + x 2 \cdot \ln (x 2))

Next Step Substitute values of Variables

∴

G id = (0.4 \cdot 71J + 0.6 \cdot 88J) + [R] \cdot 450K \cdot (0.4 \cdot \ln (0.4) + 0.6 \cdot \ln (0.6))

Next Step Substitute values of Constants

∴

G id = (0.4 \cdot 71J + 0.6 \cdot 88J) + 8.3145 \cdot 450K \cdot (0.4 \cdot \ln (0.4) + 0.6 \cdot \ln (0.6))

Next Step Prepare to Evaluate

∴

G id = (0.4 \cdot 71 + 0.6 \cdot 88) + 8.3145 \cdot 450 \cdot (0.4 \cdot \ln (0.4) + 0.6 \cdot \ln (0.6))

Next Step Evaluate

∴

G id = -2436.87865611826J

LAST Step Rounding Answer

∴

G id = -2436.8787J
