The reaction rate for a process that follows the rate law rate=k[A]2[B] is 4.0×10−4M⋅s−1 when [A]=0.20M and [B]=0.10M at a fixed temperature. What is the predicted initial rate when [A]=0.10M and [B]=0.30M while the temperature remains the same?
a) 1.8×10−3M⋅s−1
b) 1.0×10−4M⋅s−1
c) 3.0×10−4M⋅s−1
d) 6.0×10−4M⋅s−1
