Please help: **Chemical Reaction Analysis**Consider the reaction: \[ 2 \text{NO}_2 \, (g) \rightarrow \text{NO}_3 \, (g) + \text{NO} \, (g) \]This reaction entails the transformation of 2 moles of $\text{NO}_2$ gas into 1 mole of $\text{NO}_3$ gas and 1 mole of $\text{NO}$ gas.At 380 K, the activation energy for the forward reaction is 212 kJ, while the activation energy for the reverse reaction is 175 kJ. Based on this information, the following statements are presented for evaluation:- **(a)** Increasing the concentration of $\text{NO}_2$ results in an increase in the rate constant of the forward reaction. - **(b)** The forward reaction is an endothermic reaction. - **(c)** Adding a catalyst to accelerate the reaction decreases the activation energy of the reverse reaction, while the activation energy of the forward reaction remains unchanged. - **(d)** Adding a catalyst to accelerate the reaction decreases the activation energy of the forward reaction, while the activation energy of the reverse reaction remains unchanged. - **(e)** The reverse reaction is an endothermic reaction.**Explanation:**Consider each statement in the context of chemical kinetics and thermodynamics, particularly focusing on how changes in concentration, catalysts, and energy profiles affect reaction rates and pathways.

Consider the reaction: 2 NO2 (g) → NO3 (g) + NO (g) with 2-mol NO2 (9) transformed into 1-mol NO3 (g) and 1-mol NO (g). At 380 K, the activation energy of the forward reaction is 212 kJ, and the activation energy of the reverse reaction is 175 kJ. Based on the information given here, which of the following statements is correct? By increasing the concentration of NO2, the rate constant of the forward reaction increases. O b. The forward reaction of this reaction is an endothermic reaction. By adding a catalyst to speed up the reaction, the activation energy of the reverse reaction decreases and the activation energy of the forward reaction stays the same. By adding a catalyst to speed up the reaction, the activation energy of the forward reaction decreases and the activation energy of the reverse reaction stays the same. O e. The reverse reaction of this reaction is an endothermic reaction.
