Answer:
false
Explanation:
a linear equation always graphs a straight line
Answer: 2
Explanation:
1) Table (given):
<span>Initial Concentration mol/L Initial Concentration mol/ Initial Rate mol/Ls
[A] [B]
0.20 0.10 20
0.20 0.20 40
0.40 0.20 160
2) Procedure
i) Start assuming the form of the law: r = k [A]ᵃ [B]ᵇ
ii) Comparing row 2 with row 3, you infere that doubling the initial concentration of A and keeping the concentration of B constant, the speed of the reaction quadruples.
That means that the exponent a, or the order of reaction for the reactant A is 2.

I think it is B. Because A has nothing to do with chemical changes because any change takes an amount of time, C because in a mixture different compounds are involved, It could be D though but A new substance is produced in other changes too thus it must be B.
