Explain the photodecomposition of ascorbic acid

Reference no: EM13340956

Calculate the equilibrium constant for the photodecomposition of ascorbic acid (vitamin C) in a poorly packaged fruit, such as guava. 165g of guava contains 0.377g of ascorbic acid. The reduction half-reaction voltage (potential) for ascorbic acid as an antioxidant acid as an antioxidant is +0.155 volts in acid. The reduction half-reaction voltage (potential) for oxygen gas is +1.23 volts in an acidic solution. The reduction half-reaction voltage (potential) for oxygen gas in +0.40 volts in a basic solution.
