在一定条件下,可逆反应A+B⇌mC变化如图所示.已知纵坐标表示在不同温度和压强下生成物C在混合物中的质量分数,p为反应在T2温度时达到平衡后向容器加压的变化情况,回答下列问题:

(1)温度T1______T2(填“>”“=”或“<”).

(2)正反应是______反应(填“吸热”或“放热”).

(3)如果A、B、C均为气体,则m______ 2(填“>”“=”或“<”).

(4)当温度和容积不变时,如在平衡体系中加入一定量的某稀有气体,则体系的压强______(填“增大”“减小”或“不变”),平衡______移动(填“向正反应方向”“向逆反应方向”或“不”).

(5)已知2A(g)+B(g)⇌2C(g)△H=-a  kJ•mol-1(a>0),在一个有催化剂的固定容积的容器中加入2mol A和1mol B,在500℃时充分反应达平衡后C的浓度为ω mol/L,放出热量b kJ.

①a______b(填“>”“=”或“<”).

②若将反应温度升高到700℃,该反应的平衡常数将______(填“增大”“减小”或“不变”).

③在上述容器中为使该反应的反应速率增大,且平衡向正反应方向移动的可采取的措施是______(说出一种即可)
