Onsider the following reaction: chcl3(g) cl2(g)→ccl4(g) hcl(g) the initial rate of the reaction is measured at several different concentrations of the reactants with the following results: [chcl3](m) [cl2](m) initial rate (m/s) 0.010 0.010 0.0034 0.020 0.010 0.0068 0.020 0.020 0.0096 0.040 0.040 0.027 you may want to reference (pages 593 - 598) section 14.4 while completing this problem.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
