I assume this is the reaction you are talking about:
CH4 + H2O (g) --> CO(g) + 3H2(g)
From thermodynamics you can approximate the standard heat of reaction Hrxn with Hess' Law. This is the sum of the heats of formations of the products minus the sum of the heats of formations of the reactants in their stoichemtric ratios.
Hrxn = SUM [(3)*Hf (H2)+(1)*Hf(CO)] - SUM [(1)*Hf (CH4) + (1)*Hf(H2O (g))]
Looking up these values in a Chemical Engineering Handbook or textbook we can substitue and find the heat of reaction.
Hrxn = SUM [(3)*(0 kJ/mol) + (1)*(-110.52 kJ/mol)] - SUM [(1)*(-74.85 kJ/mol) +
(1)*(-241.83 kJ/mol)]
= -110.52 - (-316.68) kJ/mol
= + 206.16 kJ/mol, therefore the reaction is endothermic
Remember standard heats of formation of elements, as hydrogen in this case, are zero.

Is water vapor condensing on a glass exothermic or endothermic?
Steam itself is not endothermic or exothermic - only chemical reactions can be labelled as exothermic or endothermic the reaction whithin the steam can only be exothermic or endothermic
How water gas is prepared?
Water gas is prepared by reacting steam with a carbon-containing material, such as coal or natural gas, at high temperatures (700-1100°C) in the presence of a catalyst like nickel. This process, called steam reforming, produces a mixture of carbon monoxide and hydrogen gas.
Is mist forming on a mirror endothermic or exothermic?
The creation of "mist" or steam (condensation) from water is exothermic but the mirror is not experiencing any kind of chemical reaction.
Is steam a natural resource?
Steam itself is not considered a natural resource, but it can be generated using natural resources like water and heat. Natural steam sources, such as geothermal vents, are considered natural resources.
Is steam a natural gas?
no
What is the heat of reaction of methane in steam reforming?
The heat of reaction for methane steam reforming is an endothermic process, meaning heat is required for the reaction to occur. The reaction produces hydrogen and carbon monoxide from methane and steam. The heat of reaction for this process is around 206 kJ/mol of methane converted.
Synthesis gas production by steam reforming?
Steam reforming is a widely used method for producing synthesis gas (syngas), which is a mixture of hydrogen and carbon monoxide. In this process, natural gas is reacted with steam at high temperatures to produce syngas, which is a versatile building block for various chemical processes, such as producing ammonia or methanol. Catalysts are often employed to enhance the reaction rates and increase the efficiency of syngas production via steam reforming.

What methods of industrial preparation of hydrogen which involves water?
Two common methods for industrial preparation of hydrogen from water are electrolysis and steam reforming. Electrolysis involves passing an electric current through water to split it into hydrogen and oxygen. Steam reforming involves reacting steam with a hydrocarbon fuel, such as natural gas, at high temperatures to produce hydrogen gas.
How can you make hydrogen from other chemicals?
Hydrogen can be produced from other chemicals through processes like steam reforming of natural gas or electrolysis of water. In steam reforming, natural gas is reacted with steam at high temperatures to produce hydrogen and carbon dioxide. Electrolysis involves passing an electric current through water to split it into hydrogen and oxygen.
Is mist forming on a mirror endothermic or exothermic?
The creation of "mist" or steam (condensation) from water is exothermic but the mirror is not experiencing any kind of chemical reaction.
Is conversion of steam to water an exothermic reaction?
Yes, the conversion of steam to water is an exothermic process. When steam condenses into water, it releases heat energy to the surroundings. This heat energy is given off as the steam loses its kinetic energy during the phase change.
How you separate hydrogen from air?
Hydrogen can be separated from air through a process called electrolysis, where an electric current is passed through water to split it into hydrogen and oxygen gas. Another method is through steam reforming, where a high-temperature reaction with steam is used to break down natural gas into hydrogen and carbon dioxide.
How is hydrogen made commercially?
Hydrogen is commercially produced through processes like steam methane reforming, electrolysis of water, and coal gasification. Steam methane reforming is the most common method and involves reacting steam with natural gas to produce hydrogen and carbon monoxide. Electrolysis of water splits water molecules into hydrogen and oxygen using electricity. Coal gasification also produces hydrogen by converting coal into a gas mixture containing hydrogen.
The heat energy content of the reactants of an endothermic reaction compared with products is?
In an exothermic reaction the reactants release energy to the environment when they react - like coal burning. In an endothermic reaction the reactants need to absorb energy from their environment when they react, so the reaction feels cold in your hand, or else you have to heat it continually to make it react. The products would then be at a higher energy level than the reactant were. Photosynthesis is an interesting example of an endothermic reaction, because in this example the energy supplied to make the reaction go is not heat but light. The product (sugar) is an 'energy store' which the plant (or whatever eats the plant) can use later on to release the energy in respiration.
How is Methanol produced?
Methanol is the simplest alcohol compound, comprised of one carbon atom, oneoxygen atom and fourhydrogen atoms (CH3OH). It is also referred to as wood alcohol, carbonyl and methyl alcohol.
