Consider the equilibrium
At 1000 K and a const. total pressure of 2 bar, C2H6 is introduced into a reaction vessel. the total pressure is held const. at 2 bar and at equilibrium the composition of the mixture in mole percent is H2(g): 20.4%, C2H4 (g): 20.4%, and C2H6 (g): 59.2%.
Calculate Kp at 1000 K
if ΔH of reaction = 137 kJ/mol, calculate the value of Kp at 298.15K
Calculate ΔG of reaction for this reaction at 298.15 K

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
