1. Synthesis of compound in the gaseous phase reaction has been studied at two temperatures. At 298 K, the kp value is 1.22×10-3 and at 498 K the kp value is 2.16. Calculate the standard enthalpy change of this chemical reaction. Where value of R is 1.987Cal K-1mol-1.
1.987 CalK-1mol-1 = 8.314 Jmol-1K-1
Answer: H = 46139 J.
