<span>The reaction rate increases.
Why </span><span>Well a catalyst usually lower the activation barrier in an energy diagram. The lower and smaller that gap means the reaction is taking place rapidly compared to when that activation barrier gap is higher. </span>
Answer:
The answer to your question is 2.32 atm
Explanation:
Data
P = ?
n = 0.214
V = 2.53 L
T = 61°C
R = 0.082 atm L/mol°K
Formula
PV = nTR
solve for P
P = nRT/V
Process
1.- Calculate the temperature in K
°K = °C + 273
°K = 61 + 273
= 334
2.- Substitution
P = (0.214 x 0.082 x 334) / 2.53
3.- Simplification
P = 5.86/2.53
4.- Result
P = 2.32 atm
Answer: 12.011g/mol
Explanation: The molar mass of any element is usually stated at the bottom of periodic table (depending of your table anyways). Remember that the periodic table speaks to you in moles so every molar mass under the element is for 1 mole. By this I mean for example, 1 mole of Carbon = 12.011g of Carbon.
Answer:
The option which best describes the riders is :
Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating
Explanation:
Franklin is not accelerating as the final velocity (50 km/h) is equal to the initial velocity (50 km/h) , rather he is moving at a constant speed.
Acceleration = (final velocity - initial velocity) / (final time - initial time)
According to acceleration formula given above , the rate at which Gabriella is slowing down is 2.3 km/h and the rate at which Kendall is speeding up is also 2.3 km/h.
Hence the option stating "Gabriella is is slowing down at the same rate that Kendall is speeding up and Franklin is not accelerating" is true and it best describes the riders.
