No, it won't change the amount of reactants nor the products as a catalyst will only provide an alternative path where lower activation energy is needed for the process to take place.
hope this explains it
If it does, please give it a brainliest :)))
Answer : The velocity of the spaceship is, 
Solution :
As we are given that,
The speed of a spaceship = 7.58 wraps
So, 
The speed of light = 
Now put the value of speed of light in above expression, we get
So, 
The velocity of the spaceship = 
Now we have to convert the velocity of the spaceship m/s to cm/min.
Conversion :
(1 m = 100 cm)
(1 min = 60 sec)
The velocity of the spaceship = 
Therefore, the velocity of the spaceship is,
The boiling point is the temperature at which the vapour pressure of the solution or solvent becuase equal to the ambient pressure, and bubbles of vapour from directly in the liquid. The normal boiling point is specified when the ambient pressure ( And also thvapour pressure of the boiling liquid) is One atmosphere. Ans so where strong intermolecular forces of attraction operate for instance in Hydrogen-Bonded liquids, boiling point should be elevated. More energy has to be put into the system to disrupt the intermolecular force. And the best indicator or intermolecular or inter-particle force is boiling point.
Reverse the 2nd reaction,
CO2 + H2 -------> CO + H2O---- i
Now new equilibrium constant will be,
K' = 1/K2 = 10^-5
Adding i and last equation you'll get,
<span>CO2 (g) + 3 H2 (g)----->CH3OH (g) + H2O (g)
K1 = K' x K3 = 1.4 x 10^2 </span>
The standard temperature and pressure is 273 K and 1 atm. Since, pressure is not changed we can use Charle's law for the calculations.
<span>Charle's law says "at a constant pressure, the volume of a fixed amount
of gas is directly proportional to its absolute temperature".
V α T
Where V is the volume and T is the temperature
in Kelvin of the gas. We can use this for two situations as,
V</span>₁/T₁ = V₂/T₂<span>
</span>V₁ =
806 mL<span>
T</span>₁ =
26 ⁰C = 299 K
V₂ <span>=
? </span><span>
T</span>₂ =
273 K<span>
<span>
By applying the
formula,
</span></span>(806 mL / 299 K) = (V₂ / 273 K)
V₂ = 735. 91 mL
<span>
Hence, the answer is "a".</span>
