Question

When studying the same reaction at different temperatures, which rate constant value is associated with the HIGHEST temperature? a) 0.046 M's b) 0.023 M's c) Can't tell without knowing initial rates d) Can't tell without knowing the balanced equation e) Both c) and d)

Answer 1

An increase in temperature increases the rate constant and hence the rate. An increase in concentration increases the rate but not the rate constant.

So at different temperature rate constant of same reaction have different value at high temperature it has high valu and low temperature it has low value.

Option b is correct answer because it has highest value 0.023M-1S-1.
