Acetylene, c2h2, can be converted to ethane, c2h6, by a process known as hydrogenation. the reaction is c2h2(g)+2h2(g)⇌c2h6(g) given the following data at standard conditions (all pressures equal to 1 atm and the common reference temperature 298 k), what is the value of kp for this reaction?

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
