Which of the following is a strong acid

HCI (Hydrochloric acid)

An increase in temperature will cause the rate of a chemical reaction to

increased temperture causes rate or reaction to increase.

What is the equation for reaction rate

For a reaction whose slowest step is

mX + nY ----> aXY

rate = k * [X]m * [Y]n

where k is the rate constant; brackets represent concentrations; m and n are exponents on the concentrations of X and Y, respectively

Which equation is an expression of the rate law

Rate = k[A]m[B]n
