$N_2O$
$CO_2$
The gas which is the major contributor to global warming is carbon dioxide, represented as \( CO_2 \).
Carbon dioxide is released in large quantities due to the burning of fossil fuels, deforestation, and various industrial processes. It traps heat in the atmosphere, leading to the greenhouse effect and consequently to global warming.
Correct Answer: (E) \( CO_2 \)
For the reaction:
\[ 2A + B \rightarrow 2C + D \]
The following kinetic data were obtained for three different experiments performed at the same temperature:
\[ \begin{array}{|c|c|c|c|} \hline \text{Experiment} & [A]_0 \, (\text{M}) & [B]_0 \, (\text{M}) & \text{Initial rate} \, (\text{M/s}) \\ \hline I & 0.10 & 0.10 & 0.10 \\ II & 0.20 & 0.10 & 0.40 \\ III & 0.20 & 0.20 & 0.40 \\ \hline \end{array} \]
The total order and order in [B] for the reaction are respectively:
