For the reaction, 2SO2(g) + O2(g) => 2SO3(g), suggest the optimal conditions to maximise yield of SO3 when the forward reaction is exothermic.

So the most important thing to answer this question is to understand how an equilibrium works: it will always try to counteract the change you are making. For example, if you add more SO3 into ...

50.0 g of propene reacts with hydrochloric acid to produce 1-chloropropane. Calculate the percentage yield if only 54.0g is made.

STEPS:Write the equation CH3CHCH2 + HCl -> CH3CH2CH2Cl + H2 (where 1-chloropropane made by electrophilic addition reaction)Identify number of moles of propene used. So number of moles is m/ Mr= 50.0g ...

Explain why chlorine is more reactive than iodine.

Halogen atoms like chlorine and iodine usually react by gaining an electron to fill their outer energy level in order to resemble the noble gases which are more stable. Chlorine is a smaller atom than iod...
