(b) Some bond energies are given. bond bond energy / kJmol–1 S=O (in SO2) 534 O=O 496 Use the data, and the enthalpy change for the conversion of sulfur dioxide into sulfur trioxide, to calculate a value for the S=O bond energy in SO3. S=O bond energy in SO3 = .............................. kJmol–1 [2]
Start by writing out the balanced chemical equation, then work out how much energy is required to break all the bonds, then how much energy is released when all the new bonds are formed
2.00 moles of nitrogen and 3.00 moles of hydrogen were put in a vessel and left to reach equilibrium. At equilibrium, the pressure was 2.00 × 107Pa and the mixture contained 1.60 moles of ammonia. Calculate Kp. Include the units.

Is this your homework question from school?
Sadly your teacher would be disappointed with you asking strangers to solve the question for you
