Question 136

Multiple Choice

What is the overall standard free-energy change for the following two reactions?
A + B $\to$ 2 C
$What is the overall standard free-energy change for the following two reactions? A + B \to 2 C = \Delta G1 C + D \to E = \Delta G2 A) \Delta G1 + \Delta G2 B) \Delta G1 + 2 \Delta G2 C) \Delta G2 - \Delta G1 D) 2 \Delta G2 - \Delta G1 E) \Delta G1 \Delta G22$ = $\Delta$ G₁

C + D $\to$ E
$What is the overall standard free-energy change for the following two reactions? A + B \to 2 C = \Delta G1 C + D \to E = \Delta G2 A) \Delta G1 + \Delta G2 B) \Delta G1 + 2 \Delta G2 C) \Delta G2 - \Delta G1 D) 2 \Delta G2 - \Delta G1 E) \Delta G1 \Delta G22$ = $\Delta$ G₂

A) " $\Delta$ G₁ + $\Delta$ G₂"
B) " $\Delta$ G₁ + 2 $\Delta$ G₂"
C) " $\Delta$ G₂ - $\Delta$ G₁"
D) "2 $\Delta$ G₂ - $\Delta$ G₁"
E) " $\Delta$ G₁ $\Delta$ G₂²"
