Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: During the transportation of gases, about 20-25 percent of CO$$_2$$ is carried by Haemoglobin as carbamino-haemoglobin.
Reason R: This binding is related to high pCO$$_2$$ and low pO$$_2$$ in tissues.
In the light of the above statements, choose the correct answer from the options given below.
The correct decreasing order of atomic radii (pm) of $$\mathrm{Li}, \mathrm{Be}, \mathrm{B}$$ and $$\mathrm{C}$$ is
Following data is for a reaction between reactants A and B :
Rate $$\mathrm{mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}$$ |
$$\mathrm{[A]}$$ | $$\mathrm{[B]}$$ |
---|---|---|
$$ 2 \times 10^{-3} $$ |
0.1 M | 0.1 M |
$$ 4 \times 10^{-3} $$ |
0.2 M | 0.1 M |
$$ 1.6 \times 10^{-2} $$ |
0.2 M | 0.2 M |
$$ \text { The order of the reaction with respect to } \mathrm{A} \text { and } \mathrm{B} \text {, respectively, are } $$
