Answer:
Catalyst speeds up the chemical reactions. Catalyst is the compound that adds to the chemical reaction so that it happen more quickly. Catalyst without being consumed in the reaction accelerates the reaction. It lowers down the activation energy of the transition state and thus accelerates the reaction.

Answer:
For the formation of nitrogen dioxide, the reactants used are nitrogen monoxide and oxygen gas. 2 moles of nitrogen monoxide gas react with 1 mole of oxygen gas to produce 2 moles of nitrogen dioxide gas.
Explanation:
Answer:
yes, it is a tenth of a centimeter
Explanation:
Moles of gas = 0.123
<h3>Further explanation</h3>
In general, the gas equation can be written
![\large {\boxed {\bold {PV = nRT}}}](https://tex.z-dn.net/?f=%5Clarge%20%7B%5Cboxed%20%7B%5Cbold%20%7BPV%20%3D%20nRT%7D%7D%7D)
where
P = pressure, atm , N/m²
V = volume, liter
n = number of moles
R = gas constant = 0.082 l.atm / mol K (P= atm, v= liter),or 8,314 J/mol K (P=Pa or N/m2, v= m³)
T = temperature, Kelvin
Volume(V) =2.5 L
Pressure(P) = 1.2 atm
Temperature(T) = 25 + 273=298 K
![\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{1.2\times 2.5}{0.082\times 298}\\\\n=0.123~moles](https://tex.z-dn.net/?f=%5Ctt%20n%3D%5Cdfrac%7BPV%7D%7BRT%7D%5C%5C%5C%5Cn%3D%5Cdfrac%7B1.2%5Ctimes%202.5%7D%7B0.082%5Ctimes%20298%7D%5C%5C%5C%5Cn%3D0.123~moles)
