Question

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

Explanation:

Reaction rate is affected by concentration and temperature. Higher concentration and higher temperature increase reaction rate. The third option has 2.0 M (higher concentration than 1.0 M) and 55°C (higher than 30°C and 20°C), so it has the fastest reaction rate.

Answer:

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