Hydrogen specific heat capacity

A catalytic hydrogenation is performed at constant pressure in a semi-batch reactor. The reaction temperature is 80 °C. Under these conditions, the reaction rate is lOmmolT s-1 and the reaction may be considered to follow a zero-order rate law. The enthalpy of the reaction is 540 kj moT1. The charge volume is 5 m3 and the heat exchange area of the reactor 10 m2. The specific heat capacity of water is 4.2kJkg 1K 1. 

The new gas was found to be almost twenty times more dense than hydrogen. Ramsay found that the ratio of its specific heat capacities was 1.66, indicating that the gas was monatomic, and it therefore followed that its atomic weight was nearly 40. All attempts to induce the new gas to combine chemically met with failure. 

We can obtain the following information on hydrogen sulfide molecular weight = 34.08 specific heat capacity (Cp) = 1.02 kJ (kg K) (at...
