Rate = k[A][B]
This means the rate is directly proportional to the concentration of A and B, i.e. first order in both.
So, if [A] doubles, and [B] stays the same, the rate will double.
If [B] doubles, and [A] stays the same, the rate will double.
If both [A] and [B] double, the rate will increase by 4 times.
You can see this mathematically from the rate law as follows:
Rate = k[2][2] = 4k and since k is constant, the rate will be 4x what it was when the [A] and [B] were each 1.
We have gravity here on earth while in space there’s none
B
Explanation:
cause carbon is less than all of them in periodic table which therefore least in the group
Ketchup is not a smoothie. Unlike smoothies, ketchup is cooked.
Answer:
0.06mole
Explanation:
Given parameters:
Volume of balloon = 2.5L
T = 343.5K
P = 66.7kPa; in atm gives = 0.66atm
Unknown:
Number of moles of He = ?
Solution:
To solve this problem, we use the ideal gas equation.
It is mathematically expressed as;
Pv = nRT
where p is the pressure
v is the volume
n is the number of moles
R is the gas constant
T is the temperature
0.66 x 2.5 = n x 0.082 x 343.5
n = 0.06mole
