Increasing the temperature, as noted in the graph, increases the rate of this chemical reaction. What is the relationship betwee

n increased temperature and activation energy in a typical chemical reaction? A) As the kinetic energy of the substances increases, the overall activation energy also increases. B) The proportion of collisions that can overcome the activation energy for the reaction increases with temperature. C) Although the average kinetic energy of the colliding substances increases, this has no influence on activation energy. D) The proportion of collisions that can overcome the activation energy for the reaction decreases as temperature increases.

Answer: (C) Although the average kinetic energy of the colliding substances increases, this has no influence on activation energy.

Explanation:

After increasing the temperature of the reaction , the rate of the chemical reaction increases due to increase in the average kinetic energy of the particles. At increased temperature high proportions of particles can react making the reaction faster.

Vlad [161]

Answer:

Robert Boyle discovered Boyle’s law, which Denotes that the volume and pressure of a gas are proportionally related. He dispelled the four-element theory of Aristotle, which states  that everything is made up of earth, water, air, and fire. He also dispelled the three-principle theory of Paracelsus.

A certain gasol occupies a volume of 12.5 L at 50 degree Celsius and 740 torr. what would its volume be at STP? do the equation
Charra [1.4K]

n=PV/RT

convert:

740 torr to atm (1 atm=760 torr)

50 degree celsius to kelvin ( degree celsus +273= kelvin)

n=(0.9737 atm)(12.5L)÷(0.08206 L atm mol ⁻¹k⁻¹) (323 K)

n=0.4592 mols×22.4 L/1 mol.   (22.4 L STP= 1 mol)

=10.286 L at STP

it could be this

using the chemical stoichiometry, determine the number of moles of carbonic acid that can be produced from 4 mol of NaHCO3 and 8
Pavlova-9 [17]
Reaction is NaHCO3 + HCL = H2CO3 + NaCl
the ratios are 1:1 

the 8 moles of HCl are in excess

so if you use 4 moles of NaHCO3 then you will obtain 4 moles of carbonic acid

hope that helps
