Answer:
The reaction ca occur at 10 degree Celsius or -14 degree Celsius.                                          
Step-by-step explanation:
We are given the following in the question:
The completion of a chemical reaction is expressed by the equation

where y is  the number of seconds needed to complete the reaction and x is the temperature in degrees Celsius  at which the reaction occurs.
We have to find the temperature at which the reaction occurs, if the completion time of reaction is 160 seconds.
Putting y = 160 

Thus, the reaction ca occur at 10 degree Celsius or -14 degree Celsius.
