WebElements that exist as gases at room temperature and pressure are clustered on the right side of the periodic table; they occur as either monatomic gases (the noble gases) or diatomic molecules (some halogens, N 2, O 2). Many inorganic and organic compounds with four or fewer nonhydrogen atoms are also gases at room temperature and pressure. WebThe decomposition of a generic diatomic element in its standard state is represented by the equation 1/2 X2(g) X(g) Assume that the standard molar Gibbs energy of formation of X(g) is 4.34 kJ·mol−1 at 2000. K and−50.82 kJ·mol−1 at 30003000. K. Determine the value of the thermodynamic equilibrium constant, K, at each temperature.
