Question

which combination of factors would result in the fastest reaction rate? 2.0 m nitric acid at 55° c with a silver ribbon 1.0 m nitric acid at 20° c with a silver ribbon 1.0 m nitric acid at 30° c with a silver ribbon

Explanation:

Step1: Analyze concentration effect

Reaction rate increases with higher reactant concentration. 2.0 M is higher than 1.0 M.

Step2: Analyze temperature effect

Reaction rate increases with higher temperature. 55°C is higher than 20°C and 30°C.

Step3: Compare options

The first option has the highest concentration (2.0 M) and highest temperature (55°C), so it should have the fastest reaction rate.

Answer:

2.0 M nitric acid at 55° C with a silver ribbon
