A particle is fired at a target nucleus in which a reaction that could occur has a negative Q value.Which of the following statements is true?
A)The kinetic energy of the bombarding particle can be any amount for the reaction to occur.
B)The kinetic energy of the bombarding particle must be equal to the absolute value of the Q value for the reaction to occur.
C)The kinetic energy of the bombarding particle was greater than the absolute value of the Q value if the reaction occurred.
D)The Q value has nothing to do with whether or not the reaction can occur.
