Question

In order for a chemical reaction to take place, the Fahrenheit temperature of the reagents must be at least $139.43 ^ { \circ } \mathrm { F }$. Find the Celsius temperatures at which the reaction may occur. $\left( \mathrm { F } = \frac { 9 } { 5 } \mathrm { C } + 32 \right)$
A) $C \leq 59.68 ^ { \circ }$
B) $\mathrm { C } < 282.97 ^ { \circ }$
C) $\mathrm { C } \geq 282.97 ^ { \circ }$
D) $C \geq 59.68 ^ { \circ }$

To convert $139.43^\circ F$ to Celsius, use the formula $C = \frac{5}{9}(F - 32)$. Substituting $139.43$ for $F$, we get $C = \frac{5}{9}(139.43 - 32) = \frac{5}{9}(107.43) = 59.68^\circ C$. Therefore, the reaction occurs at temperatures $C \geq 59.68^\circ$.
