WebThe decay period of the decomposition of doped silver carbonate powder obeyed a first-order rate law. The first-order rate constants can be described by the equation: k(sec −1) = 1.52 × 10 8 exp (−22,700/RT). When pellets of pressed powder were decomposed, good agreement was found between the experimental decomposition rate and the rate ...
WebIf wet silver carbonate is dried in a stream of hot air, the air must have a certain concentration level of carbon dioxide to prevent silver carbonate from decomposing by the reaction. Δ H ° for this reaction is 79.14 kJ/mol in the temperature range of 25 to 125°C. Given that the partial pressure of carbon dioxide in equilibrium with pure ...
