(c)The standard molar enthalpy change for the reaction between calcium oxide and hydrochloric acid is -196.8 kJ mol-1.(i) Suggest three reasons why the calculated value in part (b) is different from this value.(3)Reason 1Reason 2Reason 3(ii) Using the standard enthalpy change of -196.8...
Then, the values from the standard enthalpy of formation table are multiplied by their stoichiometric coefficients and added together to calculate the overall enthalpy change of the reaction. The sign before the standard enthalpy of formation formula indicates whether the reaction is exothermic (negative...

I am curious as to what the Standard Enthalpy of formation of Graphene is. I've noticed several highly technical papers on this subject but I got lost in the abstruse math and terminology. I am interested in the Standard Enthapies o both single layer and multi-layer graphene. I will be...
概念及术语 BET公式BETformula 1938年布鲁瑙尔(Brunauer)、埃米特(Emmett)和特勒(Teller)三人在兰格缪尔单分子层吸 附理论的基础上提出多分子层吸附理论。该理论与兰格缪尔理论的主要不同之处是吸附在固 体表面的分子存在着范德华力仍可吸附其它分子,即形成多分子层吸附。在吸附过程中不一 定待第一层吸满后再吸附...
