Calculate the standard biological Gibbs free energy for the reaction: pyruvate- + NADH + H+(aq) ---> Lactate- + NAD+ at 309 K given that the standard Gibbs free energy = -65.0 kJ/mol at this temperature. This reaction occurs under conditions of low oxygen supply, such as in muscle cells during strenuous exercise. Note: See Box 7.1 on page 164. The biological standard state has hydrogen ions at 1x10-7 molar instead of 1 M.

= Standard Gibbs free energy = -65.0 kJ/mol![[H^+]](/tpl/images/0870/7831/07acb.png)
= Biological standard state has hydrogen ions = 
![Q=\dfrac{1}{[H^+]}\\\Rightarrow Q=\dfrac{1}{10^{-7}}\\\Rightarrow Q=10^7](/tpl/images/0870/7831/5fb93.png)
