Homework Answers
6.a. The rate of chemical reaction increases if the concentration of any of the reactants is increased. This happens as the number of successful collisions between the reactants increases which ultimately leads to a faster rate.
- Combustion does take place in the air as air also comprises approx 20% of oxygen in it, but definitely if one can use pure oxygen for combustion, the rate of combustion would be higher.
6.b. Sulfur burns in air with a very weak feeble blue flame with
the emission of 
. But, if Sulfer is burnt in pure oxygen, it burns much fiercely.
So, the observation confirms the conclusion of the above
answer.
