Jul 4, 2024 · Metamorphic rock - Pressure, Temperature, & Deformation: Metamorphism results from a complex interplay between physical and chemical processes that operate on a scale ranging from micrometres (e.g., fine mineral grain sizes, thickness of intergranular fluid, diffusion distances for chemical species) to tens or hundreds of kilometres (e.g ...
Jul 1, 2024 · The Contact Process. This process is important for manufacturing sulphuric acid. A number of stages are involved but the main step is the conversation of sulphur dioxide into sulphur trioxide: 2SO2(g) + O2(g) ? 2SO3(g) The reaction is exothermic. This means that an increase in temperature will mean a decrease in the yield of sulphur trioxide.
