Final answer:

The collector current of a BJT cannot be calculated with the given values of VBE and VCE alone; additional information about the transistor's operation mode and parameters is necessary to provide an accurate value.

Step-by-step explanation:

To calculate the collector current (Ic) of a BJT transistor, we need to use the given values for Is (reverse saturation current of the base-emitter junction), Is' (transport saturation current), VBE (base-emitter voltage), and VCE (collector-emitter voltage). However, the question provides VCE which typically does not directly factor in the calculation of Ic when using the Ebers-Moll model or the simpler equations for active mode operation. Nonetheless, the main formula that relates the base-emitter voltage (VBE) and the collector current (Ic) in active mode is given by the equation:

ic = Is' × (e^(VBE/VT)-1)

where VT is the thermal voltage (approximately 26mV at room temperature). Since the transport saturation current Is' is given as 10^(-13) A and VBE is provided as 0.7 V, we need to calculate Ic using these values. Notably, the provided VCE value of 0.15 V is not typically involved in this version of the calculation unless we are considering output characteristics in which case a deeper transistor model would be required.
