**Styrene Production by Catalytic Dehydrogenation of Ethylbenzene**In this process, styrene is commonly produced by the catalytic dehydrogenation of ethylbenzene. During a particular operation, a 10:90 ethylbenzene/steam mixture (on a molar basis) is utilized. This mixture is passed over a solid catalyst bed, which is maintained at a temperature of \( T = 900 \, \text{K} \). Importantly, steam does not participate in the reaction itself and serves solely as a diluent. The process is conducted at atmospheric pressure. The task is to determine the equilibrium conversion for this procedure and to identify two beneficial effects of diluting the feed gas with steam, as opposed to using pure ethylbenzene.**Graphical Elements:**The image does not contain any graphs or diagrams. Therefore, no graphical explanation is necessary. **Note 1**: The reaction considered in this problem is ![Chemical Reaction](https://example.com/reaction.png)**Note 2**: Since some of the relevant thermochemistry data for this system is available only in tabular form at discrete temperatures from the NIST WebBook (rather than in the form of parameters of the Shomate Equation), temperature integrals can be evaluated as needed by application of the trapezoidal rule:\[\int_{T_1}^{T_2} f(T) \, dT \approx \frac{(T_2 - T_1)}{2} \left[ f(T_2) - f(T_1) \right]\]**Explanation**: The chemical reaction involves the conversion of an ethylbenzene derivative yielding a different compound and hydrogen gas (\(H_2\)). The trapezoidal rule is presented to approximate the integral of a function \(f(T)\) over a temperature interval from \(T_1\) to \(T_2\). This method is particularly useful when thermochemistry data is available at specific temperature points, allowing for numerical integration in situations where a continuous functional form is unavailable.

Styrene is commonly produced by the catalytic dehydrogenation of ethylbenzene. In a particular process, a 10:90 (on a molar basis) ethylben- zene/steam mixture is passed over a solid catalyst bed maintained at T = 900 K. Steam does not participate in any reactions and is only present as a diluent. The process operates at atmospheric pressure. Obtain the equilib- rium conversion for this process and suggest two beneficial effects of dilut- ing the feed gas with steam, when compared to feeding pure ethylbenzene.

The equilibrium constant for the thermal decomposition of NO2 is 7.32 10-6 at 450 K. If a reaction vessel at this temperature initially contains 0.515 atm of NO2, what will the partial pressures of NO2, NO, and O2 be when equilibrium has been established? Since Kp is small, you can use simplifying assumptions. Be sure not to round your numbers during the calculation and use at least 3 sig figs.

In a batch reactor, reactant A is steadily converted into product B. The initialconcentration of reactant A is 100 mg/L. During a 10-hour reaction course, it wasobserved that the concentration of A in the reactor decreased at a constant rate of 10mg/L per hour. Based on the result, you can determine that the transformation reactionA→B follows ( ) with respect to reactant A.
