Unburned hydrocarbon on reacting with oxygen undergoes combustion reaction. However, the activation energy of this reaction is significantly high. When a catalyst like Pd is added to the reaction system, it provides active sites for the reaction to occur. It acts are a heterogeneous catalyst. It is pertinent of note that catalyst is refereed as heterogeneous, when it exist in different phase as compared to reactant and products. In present case, reactants and products are in gas phase, while catalyst is in solid phase. Due to availability of larger surface area at active site of Pd, activation energy of reaction decreases and decrease in activation energy favors higher reaction rates.
Fe⁰ + 2 H⁺¹Cl⁻¹ = Fe⁺²Cl₂⁻¹ + H₂⁰
the iron is oxidized
the hydrogen is reduced
hope this helps!
Answer: the formula is NO
Hello!
False.
The equation to calculate force, according to Newton's Second Law, is equivalent to F = m · a where:
m = mass of the object
a = acceleration of the object
Those two multiplied are equivalent to force.
