divide 5 hours 20 mins by 4,000
and ur answer is
320 mins/4000km
so
0.08
hope this helps
sorry if its wrong
Explanation:
Half life = 129s
Initial Concentration = 0.527M
Rate constant = ?
Order of reaction = ?
The half-life equation of a first-order reaction does not include a reactant concentration term. A half-life is independent of concentration and remains constant throughout the duration of the reaction.
Order of reaction = First Order
t1/2 = 0.693 / k; where k = rate constant
129 = 0.693 / k
k = 0.693 / 129 = 0.00537s-1
Answer: Thus the pressure of the air in a car tire in psi is 25.4
Explanation:
Pressure is defined as the force exerted per unit area.
Thus units of pressure can be atm or psi or Pa.
Given :
Convert 1.73 atm to psi units
1 atm = 14.7 psi
Thus 1.73 atm =
Thus the pressure of the air in a car tire in psi is 25.4
