Changing the concentration of one or more of the reactants can affect the rate of a reaction. This is TRUE, as it means there are more collisions between particles and therefore a higher probability of successful collisions, which speeds the reaction up.
Using the reactants in a fine, powder form rather than a large, chunky form will increase the rate of a chemical reaction as the surface area of the reactants will increase. Therefore, there is a higher probability of successful collisions, which speeds the reaction up.
A catalyst works by increasing the activation energy needed for a reaction. This is TRUE, and the catalyst itself is not used up.
Sorry I couldn't get back to you earlier. I usually use the Brainly app so am unable to check comments on my wall.
The solution would be like
this for this specific problem:
<span>1.0
</span>atm + 2.0 atm
+ 3.0 atm = 6.0 atm
So the partial pressure of
the helium 3.0 atm.
<span>I hope this helps and if you
have any further questions, please don’t hesitate to ask again.</span>
Matter is made of what molecules and atoms are made of
Answer:
Bond energy system will decrease.
Explanation:
When ice cube at -196 °C is dropped into ice-water at 0 °C then the heat energy transfers from ice-water to ice cube (since, heat energy always transfers from a hot body to cold body, according to the second law of thermodynamics). This transfer of heat energy into the ice cube increases the thermal energy of the ice cube however, the increase in thermal energy, weakens the bonds between atoms in the ice cube and changes the physical state of the ice cube thereby, results in the decrease in bond energy system.
