Calculate the velocity of a hydrogen and deuterium atom following the photolysis of HBr or DBr at 193 nm. The bond energy D(H-Br) is 366 KJ mol-1; assume that all the bromine atoms are produced in their lowest electronic state and that D(D-Br)=D(H-Br). Which of the noble gases would be most effective in relaxing the translationally excited H atoms? Çë¸ßÊÖ°ïæ½â´ð»òÌáʾ |
