How is enthalpy used to predict whether a reaction is endothermic or exothermic?
Radda [10]

<u>Answer:</u>

<em>329.48 KJ/mol heat is released by the combustion of 2 molof methane</em>

<u>Explanation:</u>

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)

\Delta H \ reaction=[ 2(\Delta HfCO_2)+ 4(\Delta HfH_2O)]-[2(\Delta HfCH_4)+4(\Delta HfO_2)]

                            =2 ( -(393.5 KJ)/mol)-[2( -74.6 KJ/mol)+4(-241.82 KJ/mol)]

                            = -787 KJ/mol-[ -149.2 KJ/mol-967.28 KJ/mol]

                           = -787 KJ/mol+1116.48 KJ/mol

                                          =329.48 KJ/mol

<em>In this question, </em><em>the enthalpy of formation</em><em> has positive value and hence the </em><em>reaction is endothermic</em><em> in which the heat is released. </em>

victus00 [196]

<u>Answer:</u>

The invention of agriculture, advances in medical technology that have greatly reduced the human death rate and he rapid increase in the uses of fossil fuels, fertilizers, metal ores, and other resources.

Option: (A), (C) and (D)

<u>Explanation:</u>

  • The Great Acceleration refers to the humanity’s impact upon the Earth’s geology and its ecosystems caused by continual and surge in growth of human activity.
  • It was first recorded in mid-20th century and is continuing to this day. The 'invention of agriculture', advancement in medical technology which reduced the death rate, rapid increase in use of 'fossil fuels', 'fertilizers' and other resources contributed to global changes.
  • Agriculture allowed us to produce more food and population increased rapidly.
  • Fossil fuels created a surge in production of Green House Gases and global temperature began to rise.
