Problem

t=4\text{ s}

, the temperature

T(t)

of a chemical reaction is changing at

T'(4)=0.20\,^{\circ}\!\text{C/s}

, while the concentration

C(t)

of a reactant is changing at

C'(4)=-0.05\,\text{mol}\,(\text{L}^{-1}\!\cdot\text{s}^{-1})

. Describe which quantity is changing more rapidly in magnitude and state its instantaneous rate of change with units.
