The rate constant for the decomposition of CH3CHO is 0.0105 dm^3/mol* at 700 K. If the activation energy for this reaction is 188kJ, find the rate constant at 800 K.
3.6ml of m-xylene(d=0.864 g/ml) is reacted with 0.6g of pthalic anhydride and 0.2 g of ALCL3 to obtain the product. the actual yield is 0.36g. using this data answer the following.
What is the equilibrium constant Kc for the reaction below. Assume temperature is 25oC. ( Represent the reaction below as a sum of reactions and then combine the corresponding K values to obtain Kc for the reaction below.)
At 320 K and 16 atm pressure, the molar volume of ammonia, NH3, is about 10% less than the molar volume of an ideal gas. The best explanation for actual volume being this much smaller than the ideal volume is that
