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.
Answer:
And what is your question
Explanation:
H2O is covalent so A is false.
Water is in clouds so B is false.
Water is polar so C is false.
D is correct H2O has an imbalance of e- so it is polar.
The second choice: physical change <span>because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved</span>
