[a]*[b]"

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as

The expression for for the given reaction is written as:

where a, b , c and d are respective stoichiometric coefficients for A, B, C and D.

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

there are two significant figures.
