In what way is the electronic configuration of the transition elements different from that of the non-transition elements?
Transition metals have a partially filled d-orbital. Therefore, the electronic configuration of transition elements is (n - 1)d1-10 ns0-2.
The non-transition elements either do not have a d-orbital or have a fully filled d-orbital. Therefore, the electronic configuration of non-transition elements is ns1-2 or ns2np1-6.
The rate constant for the decomposition of N2O5 at various temperatures is given below:
T/°C |
0 | 20 | 40 | 60 | 80 |
105 X K /S-1 |
0.0787 | 1.70 | 25.7 | 178 | 2140 |
Draw a graph between ln k and 1/T and calculate the values of A and Ea.
Predict the rate constant at 30 º and 50 ºC.
