The formation of phosgene by the reaction
CO + Cl2 ----------> COCl2
Appears to follow the mechanism
Cl2 <---------> 2Cl k1 forward; k-1 backward
Cl + CO <----------> COCl k2 forward; k-2 backward
COCl + Cl------> COCl2. k3. forward
Assuming the last reaction is rate limiting and that the first two pre-equilibrate, what is the rate law for this reaction?
A sample of calcium carbonate [CaCO3 (s)] absorbs 45.5 J of heat, upon which the temperature of the sample increases from 21.1C to 28.5C. If the specific heat of calcium carbonate is 0.82 J/g-K, what is the mass (in grams) of the sample
