What is the correct name for the enthalpy changes labeled x, y, and z?

A. $x$ is Atomisation of Cl;y is Ionisation of K ;z is Electron affinity of Cl
B. $x$ is Atomisation of Cl;y is Electron affinity of K;z is Ionisation of Cl
C. $x$ is Atomisation of $Cl_2$;y is Ionisation of K;z is Electron affinity of Cl
D. $x$ is Atomisation of $Cl_2$;y is Electron affinity of K;z is Ionisation of Cl


参考答案:  A


本题详细解析:
Atomisation is defined as the formation of w /fii;s 9qd1-k,wkmwone mole of gaseous atoms.Ionization is the process in which one mole of electrons is removed from one mole of gaseous atoms/ions.Electron affinity is the addition of one mole of electrons to gaseous atodw ,9qfs- i /;mkwwk1ims/ions.
