Which of the following statements about the effect of temperature on reaction rates is true? high temperatures can change the ah between reactants and products the value of k in a rate law does not change at different temperatures high temperatures can decrease the activation energy of a reaction, increasing the reaction rate high temperatures increase the average kinetic energy of particles, increasing the reaction rate question 11 1 pts what are the units of k for the following rate law? rate k [a] [b] = m/s 1/s 1/(m2 s) 1/(m*s)

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 :

points
