The reform reaction between steam and gaseous methane (CH4) produces "synthesis gas," a mixture of carbon monoxide gas and dihydrogen gas. Synthesis gas is one of the most widely used industrial chemicals, and is the major industrial source of hydrogen.
Suppose a chemical engineer studying a new catalyst for the reform reaction finds that 924 liters per second of methane are consumed when the reaction is run at 261°C and 0.96atm. Calculate the rate at which dihydrogen is being produced. Give your answer in kilograms per second. Round your answer to 2 significant digits.
Answer: The rate at which dihydrogen is being produced is 0.12 kg/sec
Explanation:
The balanced chemical equation is ;
According to ideal gas equation:
P = pressure of gas = 0.96 atm
V = Volume of gas = 924 L
n = number of moles
R = gas constant =
T =temperature =
According to stoichiometry:
1 mole of methane produces = 3 moles of hydrogen
Thus 20.2 moles of methane produces = 
moles of hydrogen
Mass of hydrogen =
Thus the rate at which dihydrogen is being produced is 0.12 kg/sec
Answer: Option A.
∆H is less than (more negative)∆ E of the system
Explanation:
From the question, a solid yield a mixture of gases in an exothermic reaction. Exothermic reaction is a process that give out energy after the reaction, it is mostly represented by negative H, that is enthalpy .
The enthalpy is negative( ∆H) when the reaction release energy meaning that the energy that must be absorbed to break the bonds of the reactants is greater than than energy released when new bonds are formed.
From the reaction more heat is released.
Answer:
A There are more particles in the air for water vapor to cluster around.
Explanation:
- As the condensation process takes place more particles are added to the atmosphere for water vapour and condensation further leads to the build-up of clouds.
- If the sky is polluted with pollutants the condensation can raise the level of pollution by blocking the rays of the sun from reaching the ground. This affects the visibility of most of the cities.
The answer is Cc reactants break bonds and form new bonds to make new substances
