Which rate constant would result in the fastest reaction?

A. 1.3 × 10^3 L/mol · s
B. 2.8 L/mol · s
C. 9.5 × 10^-2 L/mol · s
D. 4.2 × 10^-3 L/mol · s

i think that it is answer c as it has the highest values plus a negative exponent

I don't agree with you. C and D are smaller numbes than A or B

To determine which rate constant would result in the fastest reaction, we need to compare the magnitudes of the rate constants. In this case, we are looking for the largest value, as a larger rate constant indicates a faster reaction.

Let's analyze the given options:
A. 1.3 × 10^3 L/mol · s
B. 2.8 L/mol · s
C. 9.5 × 10^-2 L/mol · s
D. 4.2 × 10^-3 L/mol · s

Option C has the largest value, 9.5 × 10^-2 L/mol · s. It is important to note that negative exponents indicate small values, not large values. In this case, the negative exponent (-2) means that the value is divided by 100. So, 10^-2 is actually 1/100 or 0.01. Thus, option C has a value of 9.5 × 0.01 = 0.095 L/mol · s.

Comparing the values, we see that option A (1.3 × 10^3 L/mol · s) is the largest, indicating the fastest reaction. Therefore, the correct answer is A, not C.

To summarize, the rate constant with the fastest reaction is option A, 1.3 × 10^3 L/mol · s, not option C.
