Answer #1

3) answer : d. When the reaction temperature is lowered

explanation:

the given reaction is exothermic reaction . exothermic reaction favours at low temperature. so on decrease in temperature the reaction will shift towards products side.

4) answer : b. Equilibrium is exothermic

explanation :

exothermic reaction favours to lower temperature and endothermic reaction reaction favours at high temperature . on increases in temperature the reaction shifts left means it is exothermic reaction

For the following reaction: CH4(g) + O2(g) --> CO2(g) + H2O (g) A) Using bond enthalpies from reference tables, calculate the enthalpy of this reaction. B) Is this reaction Endothermic or Exothermic? (I did this and got 228 kJ, Endothermic however someone previously on Chegg did it and got 500kJ.. our only difference was I broke one more O2 bond after balancing the equation so that I would have enough oxygen molecules for the CO2 as well as the H2O).....
