WebApr 6, 2024 · Reacting masses and volumes When solving many problems in physics at IB Diploma level it is usual to ignore friction. In a similar way when solving problems with gases chemists often tend to treat all gases as if they behave like ideal gases and ignore the fact that they do not. How valid is this assumption? early signs of cancer on skinWebConcentration. The more concentrated a reaction mass is, the less solvent per ton of product will be used, leading to a reduction in both solvent inventory and reactor size. However, this results in a lower heat sink to absorb the heat of reaction.
