Select the favourable conditions required for the formation of...

In the alveoli, where there is high ${pO}_{2}$, low ${pCO}_{2}$, lesser ${H}^{+}$concentration, and lower temperature, the factors are all favourable for the formation of oxxhaemoglobin, whereas, in the tissues, where low ${pO}_{2}$, high ${pCO}_{2}$, high ${H}^{+}$concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin.
