Problem- The gas phase reaction A + B ? C has a reaction rate which is experimentally observed to follow the relationship rate = k[A]2[B]. The overall order of the reaction
(a) is first. (b) is second. (c) is third. (d) is zero. (e) is one-half.
I need help for above question. Show each steps for the above problem.
The utilization of the British thermal unit (Btu) is common in much engineering work. A Btu is the amount of heat needed to raise the temperature of 1 lb of water by 1 degree Farenheit. Compute the number of Joules in a Btu.
