I’m going to go with The pH 1 solution is two times more acidic than that with a pH of 1. If that’s not the answer, then my second best guess would be The pH solution is ten times more acidic than that with a pH of 2.
The first and third answer choice wouldn’t even be an answer so you can just cancel those two out and pick between answer choice 2 or 4.
Hope this helps, and have an amazing day!! :))
Answer : The temperature for non-catalyzed reaction needed will be 456 K
Explanation :
Activation energy : The energy required to initiate the reaction is known as activation energy.
According to the Arrhenius equation,
Since, the rate for both the reaction are equal.
..........(1)
where,
= activation energy for non-catalyzed reaction = 75 kJ/mol
= activation energy for catalyzed reaction = 49 kJ/mol
= temperature for non-catalyzed reaction = ?
= temperature for catalyzed reaction =
Now put all the given values in the above formula 1, we get:
Therefore, the temperature for non-catalyzed reaction needed will be 456 K
Answer: use the cubic feet per hour formula (cfh)
Explanation: multiply room times height times the width times the length and that gives you the cfh and then you just divide the cfh by the volume of the room to get your answer
Answer:
The final pressure of the gas sample at constant temperature is 1.20 atm.
Explanation:
Boyle's Law : Volume occupied by fixed amount of gas at a given temperature is inversely proportional to pressure .(moles, temperature are constant )
on transposing ,
PV = constant
............(1)
Initial pressure = P1 = 2.00 atm
Final pressure = P2 = ?
Initial volume = V1 = 300.0 mL
Final volume = V2 = 500.0 mL
Putting values of P1 ,V1, V2 in equation (1) and solving for P2
P2 = 1.20 atm at constant temperature
